INTRODUCTION
SAFETY
OPERATOR SAFETY
Follow the recommended maintenance program on page 49 to ensure that all
critical components on the snow bike are thoroughly inspected at specific
intervals outlined in the Periodic Maintenance Chart. Your dealer can perform
this service.
WARNING
Driving a snow bike requires your full attention. DO NOT drink alcohol or use
drugs or medications before or while driving. They will reduce your alertness
and slow your reaction time.
Snow bikes are capable of traveling at high speeds. Use extra caution to
ensure operator safety. Make sure your snow bike is in excellent operating
condition at all times. Always check major and vital safety components before
every ride.
All Timbersled snow bikes are designed and tested to provide safe operation
when used as directed. Failure of critical machine components may result from
operation with any modifications, especially those that increase speed or
power. DO NOT MODIFY YOUR MACHINE. The snow bike may become
aerodynamically unstable at speeds higher than those for which it is designed.
Loss of control may occur at higher speeds. Modifications may also create a
safety hazard and lead to bodily injury.
HOST BIKE
The Timbersled Snow Bike system is designed to be attached to a variety of
host bikes. Read and understand your host bike’s operation manual and follow
all safety and maintenance information. Failure to do so could result in serious
injury or death.
STAY CLEAR OF TRACK
Your snow bike is propelled by a revolving track that must be partially exposed
for proper operation.
WARNING
Serious injuries may result if hands, feet, or clothing become entangled in the
track. Be alert when riding, and remain properly seated to stay clear of the
track. Never hold the snow bike up or stand behind it while warming up the
track. A loose track or flying debris could cause serious injury or death. We
recommend having your dealer perform all track service and alignment
procedures.
9
SAFETY
RIDING POSITION
Operating a Timbersled requires skill and balance for proper control. Rider
positions may vary with experience and the features available on some models,
but under many conditions the proper position is to be seated with both hands
on the handlebar grips for proper throttle, brake, and steering control. See your
host bike’s owners manual for proper riding position.
WARNING
Improper riding position may reduce control and could result in serious injury or
death. Always ride in a position that allows for control of your vehicle.
RIDER CAPACITY
This Timbersled is designed for a single rider only. Never carry a passenger on
this vehicle.
RIDING APPAREL
HELMET
Wearing a helmet can prevent a severe head injury. Whenever riding a
Timbersled vehicle, always wear a helmet that meets or exceeds established
safety standards. Clasp the buckle and pull each strap tight to ensure the helmet
is properly secured to the head.
Approved helmets in the USA and Canada bear a U.S.
Department of Transportation (DOT) label.
Approved helmets in Europe, Asia and Oceania bear
the ECE 22.05 label. The ECE mark consists of a
circle surrounding the letter E, followed by the
distinguishing number of the country which has
granted approval. The approval number and serial
number will also be displayed on the label.
10
SAFETY
EYE PROTECTION
Do not depend on eyeglasses or sunglasses for eye protection. Whenever riding
a Timbersled vehicle, always wear shatterproof goggles or use a shatterproof
helmet face shield. Timbersled recommends wearing approved Personal
Protective Equipment (PPE) bearing markings such as VESC 8, V-8, Z87.1, or
CE. Make sure protective eye wear is kept clean.
CLOTHING
Be prepared, be warm and be comfortable when riding. Be aware of the weather
forecast, especially the windchill, and dress accordingly. See page 23.
WARNING
Avoid wearing loose clothing or long scarves, which can become entangled in
moving parts and cause serious injury. Always wear an approved helmet and
eye protection.
SURVIVAL PREPARATION
For your safety, always ride in a group. Always tell someone where you're going
and how long you expect to be gone. If it isn't possible to ride with others, and
you must travel into remote areas, always carry survival equipment that's
appropriate to the conditions you may encounter. Such equipment may include,
but is not limited to: extra clothing, a sleeping bag, a flashlight, food and water, a
signaling mirror, a means of building a fire, and a two-way radio or cellular
telephone.
Always carry the owner’s manual on your snow bike. For added protection,
purchase and carry the following items on your snow bike as well:
Extra Set of Spark Plugs
Tow Rope
Extra Oil
Fuel Deicer
Winter Survival Kit
Spare Drive Chain
Spare Chain Case Chain (if
equipped)
Trail Map
First Aid Kit
Tool Kit
11
SAFETY
EXCESSIVE SPEED
WARNING
High speed driving, especially at night, could result in serious injury or death.
Always reduce speed when driving at night or in inclement weather.
Always observe all state and local laws governing snow bike operation and
speed limits. Always be alert and pay attention to the trail ahead. If your speed is
40 MPH (64 km/h), your snow bike is traveling about 60 feet (18 m) per second.
If you look back for only two seconds, your snow bike will travel about 120 feet
(36 m). If your speed is 60 MPH (96 km/h), your snow bike will travel about 180
feet (55 m) in two seconds.
Traveling at night requires extra caution. If your host bike is equipped with a
headlight, check headlight and taillight to ensure proper operation, and don’t
over-drive your headlight beam. Always be able to bring your snow bike to a
stop in the distance illuminated by the headlight.
DRIVER AWARENESS
Slow down when traveling near poles, posts, or other obstacles. Be especially
alert if you're snow biking after dark. Always be on the alert for wire fences.
Single strands are especially dangerous, since there may be a great distance
between posts. Guy wires on utility poles are also difficult to distinguish.
Make sure the way is clear before crossing railroads and other roads and
highways. The noise of your snow bike will drown out the sound of approaching
vehicles. Look ahead, behind, and to both sides before turning or crossing
railroad tracks or highways. Steep embankments may also hide your view.
Always leave yourself a way out.
Variances in snow depth and/or water currents may result in uneven ice
thickness. You may drown if you break through the ice. Never travel on frozen
bodies of water unless you have first verified that the ice is sufficiently thick to
support the weight and moving force of the snow bike, you and your cargo,
together with any other vehicles in your party. Always check with local authorities
and residents to confirm ice conditions and thickness over your entire route.
Operators assume all risk associated with ice conditions on frozen bodies of
water.
When teaching inexperienced operators to ride, set up a predetermined course
for practice. Make sure they know how to drive and control the snow bike before
allowing them to make longer trips. Teach them proper snow bike courtesy, and
enroll them in driver's training and safety courses.
12
SAFETY
DISABLED OPERATORS
Safe operation of this rider-active vehicle requires good judgement and physical
skills. Operators with cognitive or physical disabilities have an increased risk of
loss of control, which could result in serious injury or death.
MOUNTAINOUS TERRAIN RIDING
Mountainous terrain operation, even for experienced riders, can present
conditions and situations that could result in serious injury or death. Please
review all of the information about riding in mountainous terrain on the following
pages of this manual.
WARNING
An avalanche can occur at any time, in any conditions and on any slope.
The avalanche information provided in this manual should be considered basic
information and is not intended to replace your participation in an avalanche
safety training course. After reviewing the avalanche information in this manual,
be sure to participate in an avalanche safety training course before riding in
mountainous terrain. The training course will provide more information as well as
the opportunity to practice riding and using proper search and recovery
techniques.

SAFETY
GET TO KNOW YOUR SAFETY GEAR
Following the safety gear and apparel recommendations will increase your
chances of survival if you encounter an avalanche or become stranded in the
backcountry, but even experienced and properly-equipped snow bikers, hikers
and skiers perish in avalanches or succumb to hypothermia. Using a beacon or
probe for the first time during an avalanche recovery operation, or not knowing
how to deploy your avalanche air bag backpack during a slide, should be
considered UNACCEPTABLE to you and all members of your riding group. It’s
critical that you and all members of your riding group know how to use the safety
gear.
While you may know how to use your gear, you may have to rely on your
riding group to find you in an avalanche. Make sure they know how to use
their gear.
Dress in layers. Multiple layers of clothing provide the best barrier to cold and
wind. Layers can be removed, but if you start out without enough layers, they
cannot be added later. Avoid cotton materials, which will freeze if they get wet.
Wear highly visible gear.
Try on all gear and equipment to make sure it fits and doesn’t interfere with
your riding capabilities. Place all survival aids in your backpack and wear the
backpack at all times. Non-essential items can be stored on the snow bike in
an accessory bag.
Read and follow the manufacturer’s user and maintenance instructions for all
gear. If you have questions about how your gear works, contact the
manufacturer for more information.
Practice using your beacons, shovels and probes with your riding group in
real-world conditions wearing all of your gear. Have someone hide an active
“transmitting” beacon by throwing it (not walking it) into a snowbank and
timing your group’s search for it.
Test deploying your gear. If you own an avalanche air bag backpack, check
with the manufacturer’s test deployment guidelines and bottle weight
replacement specifications. Most air bag backpack manufacturers
recommend testing the pack once a year so you know it works and feel
comfortable with the bag and deployment time.
Make sure your probe and shovel are in good condition and that you know
how to assemble them.
15
SAFETY
GET THE PICTURE
Slopes steeper than 30º are more prone to avalanches, but any slope should be
considered avalanche terrain, even small slopes with trees. Low-angle slopes
are also avalanche terrain if they have steeper slopes above them.
NOTE
The 30º slope graphic is for illustration purposes only. The risk of an avalanche
is always present in mountainous terrain, regardless of slope angle.
Always look for the following warning signs of unstable snow. If you see or hear
any of these signs, riding on or below any slope is dangerous and should be
avoided:
Recent avalanches
A “whumpfing” sound under a
snowpack
Cracks across the top of a snowpack
A recent heavy snowfall
Blowing snow
Rain
Rapid warming
GET OUT OF HARM’S WAY
Before riding, always tell a responsible person (i.e. at the lodge or gas station)
where your group is going.
Never ride alone. Always ride in a small, manageable group. Riding in a large
group makes it more difficult to track riders or find missing members.
Go “one at a time”. Only one snow bike at a time should cross, ascend or
highmark a slope. Other riders should watch from a safe location until the
previous rider exits the slope.
Never park at the base of a slope or at the bottom of a gully or valley. When
parking to take a break or watch other riders, park at the sides of the slope
with the front of your snow bike pointed away from the slope.
16
SAFETY
GET TO KNOW YOUR SNOW BIKE
Because Timbersled snow bikes feature tall track paddles, the rear suspension
rails and sliders will sit above the snowpack on a groomed trail. Always deploy
the scratchers and limit high speed operation when trail riding.
Always practice riding your snow bike in a safe, open, flat area before attempting
your first ride in mountainous terrain. This is especially important for low-
elevation riders who are not accustomed to riding a snow bike designed for deep
snow.
Do not ride in mountainous terrain until you are comfortable riding and
controlling your snow bike in deep snow.
Practice turning, leaning and braking, both on the trail and off the trail. When
you’re comfortable with these maneuvers, practice more advanced
maneuvers in deep flat snow.
Learn techniques from more experienced riders.
Practice traversing through deep snow, which is when you will often need to
steer by leaning your body weight in the desired direction.
Practice using proper throttle control to maintain vehicle momentum and
adequate track speed in deep snow. Everyone gets stuck at some point in
time. If you know your snow bike is becoming stuck, try to turn downhill as
much as you can before the snow bike comes to a stop.
GET THE FORECAST
Make a riding plan based on the current avalanche
and weather forecast. It is important to remember that
overnight weather conditions may have created unsafe
riding terrain that was considered safe the day before.
Visit www.avalanche.org or scan the QR code. Follow
the page links to locate current avalanche reports and
conditions for your area of operation.

SAFETY
GET AVALANCHE SAFETY TRAINING
Timbersled recommends you and all members of your
riding group participate in an avalanche safety course.
Visit www.avalanche.org/education or scan the QR
code for education and training resources.
AVALANCHE AWARENESS
Avalanches are a matter of timing. A steep slope can be safe one day, but
unsafe the next day due to changing weather and wind conditions.
Always review the user instructions provided with your safety equipment and
follow the recommendations for maintenance, testing and use. Always test
your safety equipment to ensure it works properly before riding in
mountainous terrain.
Always store your survival gear in your backpack and wear the backpack. Do
not store your survival gear on the snowmobile.
Always research current avalanche conditions in your area of operation
before riding. Check with local law enforcement, resort or lodging personnel,
gas station attendants and other riders to learn about current conditions and
any advisories in the area.
Read and understand the avalanche danger scale. Pay attention to any
danger level warnings issued for your area of operation.
Always remain alert while riding in mountainous terrain. Be aware of
snowpack conditions above you as you ride. Avalanches can occur at any
time regardless of current condition reports.

SAFETY
ICE AND SNOW BUILD-UP
WARNING
Ice and snow build-up may interfere with the steering and braking of your snow
bike, resulting in serious injury or death. Keep the snow bike free of snow and
ice.
Before driving, manually turn the ski to the left and right to be sure ice and snow
are not interfering with full left and right steering. If difficulty is encountered,
remove ice and snow build-up that may be obstructing the steering.
DRIVING ON SLIPPERY SURFACES
WARNING
Never attempt an abrupt change of direction when operating on slippery
surfaces. Proceed slowly and use extra caution. Driving on ice or hard-packed
snow reduces steering and braking control, which may result in loss of control
and serious injury or death. Slow down and use extra caution when operating
on slippery surfaces.
INADEQUATE SNOW CONDITIONS
NOTICE
Driving in too little snow will result in excessive wear and damage to the slide
rail, track, ski, ski skags, and/or spindle.
WARNING
Inadequate cooling and lubrication will lead to overheating of the slide rail and
track, causing premature wear, damage and failure, which can result in serious
injury. Reduce speeds and frequently drive into fresh snow to allow adequate
cooling and polishing of the slide rail and track surfaces. Avoid operating for
prolonged periods on ice, hard-packed surfaces or roads.
OPERATING IN DEEP SNOW
If the snow bike becomes stuck in snow, clear the track and tunnel area of snow,
then step down the snow in front of the snow bike so that when the throttle is
opened, the snow bike will be able to climb up and over the snow.
20
SAFETY
DRIVING DOWNHILL
When riding downhill, shift your weight to the rear of the snow bike and reduce
your speed to a minimum. Apply just enough throttle to keep the engine from
stalling, allowing the engine's compression to help slow the snow bike and keep
it from rolling freely downhill.
WARNING
When driving on long downhill stretches, pump the brakes. Riding the brakes
may cause the brake system to overheat, which may result in brake failure.
Excessive or repetitive use of the brakes for high speed stops will also cause
an overheated brake system. This condition may lead to a sudden loss of
brakes and/or fire and may result in serious injury or death.
DRIVING IN HILLY TERRAIN
WARNING
Climbing a hill or crossing the face of a slope may result in loss of balance and
rollover, causing serious injury or death. Use caution and good judgement
when driving in hilly terrain.
Use extra caution when operating in hilly terrain. If climbing a hill is unavoidable,
keep your weight low and forward. If you must cross the face of a slope, keep
your weight on the uphill side of the snow bike to maintain proper balance and
avoid possible roll-over.
Slow down when reaching the crest of a hill. Be prepared to react to obstacles,
sharp drops or other people or vehicles that may be on the other side of the hill.
If you're unable to continue up a hill, turn the snow bike downhill before it loses
momentum. If this isn't possible, spin the track just enough to dig in to prevent it
from rolling back down the hill. Stop the engine. Keeping away from the downhill
side of the snow bike, pull the rear of the snow bike around and point the front
end and skis downhill. Remount the snow bike, restart the engine, and descend
the hill carefully.
COLD WEATHER DRIVE-AWAY
Whenever your snow bike has been parked for a length of time, especially
overnight, always make sure the ski and track are loosened from ice and snow
before attempting to drive. Apply the throttle with enough authority to put the
snow bike into motion, but always operate within safety limits.
CAUTION
Reference host bike’s owner’s manual to insure bike is adequately prepared
for cold temperature conditions.
21
SAFETY
MANEUVERABILITY
While much control and maneuverability is achieved through the steering
system and ski, maximum control is achieved by the shifting of your body
weight. Maneuverability will change for lighter operators.
DRIVING RESPONSIBLY
Every snow bike handles differently, and even the most benign conditions may
become dangerous if operators drive improperly. If you're new to snow biking,
acquaint yourself with the snow bike and with what it will and won't do under
various conditions. Even seasoned drivers should spend some time getting the
feel for a snow bike before attempting ambitious maneuvers.
A snow bike depends on the rider's body position for proper balance in
executing turns, traversing hills, etc. Always start on a smooth, level area to
begin building your operating experience.
Before allowing someone else to use your snow bike, know the extent of their
operating skills. Check to see if they've taken a safety course and have an
operator's certificate. For their protection, as well as yours, make sure they
take a safety course. Everyone can benefit from the course.
Don't “jumpyour snow bike over large drifts or similar terrain. Jumping may
injure your back because of spinal compression that could occur when the
snow bike impacts the ground. The seat and suspension of your snow bike
have been designed to provide protection under normal riding conditions.
Your snow bike is not intended for this kind of use.
Be courteous to oncoming traffic by dimming your headlights (if equipped)
and reducing your speed.
When traveling in a group of snow bikes, don't tailgate (follow too closely).
Leave enough distance between snow bikes to provide ample stopping room
and to provide protection from flying snow and debris. Allow even more
distance when driving on slippery surfaces or when driving in darkness or
other low visibility conditions. Be aware of any traffic around your vehicle.
Drive defensively to avoid accidents.
If equipped, remove the key from the ignition when you leave the snow bike
unattended.

THE PERFECT FIT
SUSPENSION QUICK SETUP GUIDE
The front q
and rear w
suspensions on your Timbersled snow bike are easy to
adjust. Just remember three simple steps:
1. Ride your snow bike.
2. Adjust the spring preload
e
to tune vehicle balance (ski pressure and weight
transfer).
3. Adjust shock clickers r
(if equipped) to tune ride quality (stiffer or softer
ride).
The following sections explain how to execute these steps in greater detail
according to your specific Timbersled model. For ARO models, move on to the
Timbersled ARO Suspension Quick Setup section. For RIOT models, move on
to the Timbersled RIOT Quick Setup Guide section.
NOTE
The best suspension setting depends on many variables including the riding
terrain and the rider’s weight, riding style, and individual preferences.
31
THE PERFECT FIT
TIMBERSLED ARO SUSPENSION QUICK SETUP
Step 1: Ride your Timbersled ARO snow bike.
Ride the snow bike on the type of terrain you most often intend to ride to fully
experience the existing suspension settings before making any adjustments.
Optimal suspension settings can change depending on the terrain you ride.
Step 2: Adjust the spring preload to tune vehicle balance.
CAUTION
DO NOT EXCEED MIN/MAX preload values (as shown in the tables on page
38 and page 38). Failure to comply may result in personal injury or damage to
equipment.
After riding, you should be able to determine if the snow bike needs more or less
weight transfer and ski to ground pressure. In general, the more spring preload
that is added, the less weight will be transferred. Heavier riders, will typically
require more spring preload than lighter riders.
NOTE
Always perform shock spring preload adjustments with the weight of the
vehicle removed from the shock and the shock at full extension. Make spring
preload adjustments in small (approximately 1/16th of an inch) increments and
test ride quality between adjustments.
If your ride requires less weight transfer to the rear suspension, increase
the rear track shock’s spring preload.
If your ride requires more weight transfer to the rear suspension,
decrease the rear track shock’s spring preload.
If it feels like the ski to ground pressure is too heavy, making it difficult to
steer, increase the preload on the front track spring and decrease the preload
on the back track spring.
If it feels like the ski to ground pressure is too light (i.e. the ski lifts from
the ground too readily), decrease the preload on the front track spring and
increase the preload on the back track spring.
NOTE
For Timbersled ARO bikes with monotube shocks (i.e. shocks with NO
clickers), the rear track spring preload can also be decreased to increase ride
softness and increased to increase ride stiffness and reduce bottoming out.
However, for Timbersled ARO bikes equipped with clickers, using the clickers
is typically the best way to adjust for these ride quality characteristics.
Step 3: Adjust shock clickers (if equipped) for ride quality.
32
THE PERFECT FIT
For ARO models with shock clickers, you can adjust the clickers to control
bottoming and adjust ride comfort.
NOTE
To learn more about compression and rebound damping with shock clickers,
see the sections on QS3 Shocks (page 36) and 1.5 Zero LSC-R Shocks (page
37).
For a softer ride, turn the clicker(s) counter-clockwise to decrease
compression or rebound damping.
For a stiffer ride or to stop bottoming out the front or rear suspension,
turn the front or rear track shock clicker clockwise to increase compression or
rebound damping.
Test ride the snow bike and continue making small spring and clicker
adjustments until you achieve the perfect ride.
NOTE
For improved handling and additional control of the front ski, the Timbersled
TRIO front shock can be added to the front forks and spindle of ARO and RIOT
models.
TIMBERSLED RIOT SUSPENSION QUICK SETUP
Step 1: Ride your Timbersled RIOT snow bike.
Ride the snow bike on the type of terrain you most often intend to ride to fully
experience the existing suspension settings before making any adjustments.
Optimal suspension settings can change depending on the terrain type you ride
Step 2: Adjust the spring preload to tune vehicle balance.
CAUTION
DO NOT EXCEED MIN/MAX preload values (as shown in the tables on page
38 and page 38). Failure to comply may result in personal injury or damage to
equipment.
After riding, you should be able to determine if the snow bike needs more or less
weight transfer and ski to ground pressure. In general, the more spring preload
that is added, the less weight that will be transferred. The Timbersled RIOT’s
front track shock and spring supports most of the bike’s weight, while its rear
track shock and spring primarily controls ski to ground pressure.
33
THE PERFECT FIT
NOTE
Always perform shock spring preload adjustments with the weight of the
vehicle removed from the shock and the shock at full extension. Make spring
preload adjustments in small (approximately 1/16th of an inch) increments and
test ride quality between adjustments.
If your ride requires less weight transfer, decrease the front track shock’s
spring preload.
If your ride requires more weight transfer, increase the front track shock’s
spring preload.
If it feels like the ski to ground pressure is too heavy, making it difficult to
steer, you can decrease the preload on the rear track spring.
If it feels like the ski to ground pressure is too light (i.e. the ski lifts from
the ground too readily), you can increase the preload on the rear track spring.
NOTE
For Timbersled RIOT bikes with monotube shocks (i.e. shocks with NO
clickers), the front track spring preload can also be decreased to increase ride
softness and increased to increase ride stiffness and reduce bottoming out.
However, for Timbersled RIOT bikes equipped with clickers, using the clickers
is typically the best way to adjust for these ride quality characteristics. Ski to
ground pressure can also be adjusted with the rear track shock clicker alone or
in combination with spring preload settings.
Step 3: Adjust shock clickers (if equipped) for ride quality.
For RIOT models with shock clickers, you can adjust the clickers to control
bottoming, adjust for ride comfort, and adjust ski to ground pressure. The
clickers on the front track shock should be used to increase or decrease
bottoming resistance and ride quality and the clickers on the rear track shock
should be used to increase and decrease ski to ground pressure and weight
transfer.
NOTE
To learn more about compression and rebound damping with shock clickers,
see the sections on QS3 Shocks (page 36) and 1.5 Zero LSC-R Shocks (page
37).
For a softer ride, turn the front track shock clicker counter-clockwise to
decrease compression damping.
For a stiffer ride and less bottoming, turn the front track shock clicker
clockwise to increase compression damping.
34
THE PERFECT FIT
To decrease weight transfer, turn the rear track shock clicker clockwise to
increase rear shock compression damping
To increase weight transfer, turn the rear track shock clicker counter-
clockwise to decrease rear shock compression damping
Test ride the snow bike and continue making small spring and clicker
adjustments until you achieve the perfect ride.
NOTE
For improved handling and additional control of the front ski, the Timbersled
TRIO front shock can be added to the front forks and spindle of ARO and RIOT
models.
TIMBERSLED IFP SHOCKS
All standard ARO and RIOT models have Timbersled Internal Floating Piston
(IFP) Shocks for both front track and rear track. Timbersled IFP shocks are
spring preload q
adjustable ONLY as they do not have clickers for adjusting
compression and rebound damping. Although the factory spring preload settings
are usually sufficient for most riders, if you find adjustment is needed, NEVER
adjust the spring preload beyond the minimum and maximum spring preload
settings (see page 38 and page 38).
NOTE
A spanner wrench (Part Number: 2871095–329) is needed to adjust the
Timbersled IFP shock spring preload.
35
THE PERFECT FIT
FOX QS3 SHOCKS
All Timbersled ARO LE and RIOT LE Models, including the Timbersled 3
Model, have QS3 shocks for both front track and rear track. Fox QS3 Shocks
are spring preload adjustable
q
and have clickers
w
for adjusting compression
damping. Remember to adjust your snow bike’s spring preload first, before
moving on to adjust the clickers. If spring preload adjustment is needed, never
adjust the QS3 shocks beyond their Min/Max preload values (see page 38 and
page 38). Compression damping slows down (i.e. dampens) the shock
compression that happens when the snow bike hits a dip, bump or other
disturbance. The higher the compression damping, the slower the shocks will
compress when encountering a disturbance.
QS3 clickers have the following three positions:
#1 Soft: Turn the clicker all the way to it’s farthest counterclockwise position
to achieve a softer or more plush ride with the least amount of compression
damping.
#2 Medium: Turn the clicker one click clockwise from its soft position to
achieve a intermediate ride (between plush and stiff) with a medium amount
of compression damping.
#3 Stiff: Turn the clicker two clicks clockwise from it’s soft position for a stiffer
ride with the highest amount of compression damping.
TIP
When ascending steep inclines with the Timbersled RIOT LE, temporarily turn
the rear track clicker on the QS3 shocks clockwise to it’s highest compression
damping setting to help the ski remain in contact with the ground during the
ascent.
36
THE PERFECT FIT
FOX 1.5 ZERO LSC-R SHOCKS
Timbersled ARO 120 SX Models, have FOX 1.5 Zero LSC-R Shocks for both
front and rear track. In addition to being spring preload adjustable
q, Fox 1.5
Zero LSC-R Shocks have 2 clickers which adjust compression damping
w
and
rebound damping
e. Remember to adjust your snow bike’s spring preload first,
before moving on to adjust the clickers. If spring preload adjustment is needed,
never adjust 1.5 Zero LSC-R shocks beyond their Min/Max preload values (see
page 38 and page 38).
Compression damping and rebound damping work hand-in-hand to provide a
softer or stiffer ride. Increasing compression damping creates a stiffer ride by
slowing down (i.e. dampening) the shock compression that happens when your
bike hits a dip, bump or other disturbance. Increasing rebound damping also
creates a stiffer ride by causing the shocks to rebound (i.e. extend back to their
normal position) more slowly after compressing when the bike hits a
disturbance. Too much rebound damping on bumpy terrain may not allow the
shocks to recover quickly enough after a bump to allow the shock to be ready for
the next bump.
The 1.5 Zero LSC-R shock clickers have a total of 24 compression damping
clicker positions and a total of 25 rebound damping clicker positions which
allows for more minute changes and finer tuning of ride quality. The shock
clickers can be turned all the way counterclockwise for a softer or plusher ride
with the least amount of compression or rebound damping and can be turned all
the way clockwise for the stiffest ride with the most amount of compression or
rebound damping. Keep in mind that adjustments to the spring preload will
require you to reset the compression and rebound damping to find the best
settings once again.
37
THE PERFECT FIT
NOTE
After setting the spring preload, it is suggested that you start with both
compression and rebound damping set at their softest settings (i.e. clickers
turned all the way counterclockwise) and slowly try out more compression and
rebound damping until you achieve your perfect ride.
FRONT TRACK SHOCK SPRING SETTINGS
Factory settings, combined with user adjustments to the front track shock spring,
should be sufficient in providing the best riding experience for most riders.
Always perform shock spring preload adjustments with the weight of the vehicle
removed from the shock and with the shock at full extension.
NOTICE
Never adjust spring preload to an installed length longer than the factory length
or shorter than the minimum length as shown in the following chart. Damage to
the suspension could result. When decreasing preload, make sure at least two
turns of preload are holding the retainer against the spring.

TSS SHOCK TUNING
The TSS suspension system is intended to work in harmony with the in track
rear suspension to create a dual rear suspension feel that is unique to a
Timbersled snow bike. It is not intended to have a soft squishy feel like the stock
motorcycle rear suspension, and it’s important that you do not try to tune it to
feel this way. For maximum suspension performance follow the tuning
instructions.
The TSS shock is preset from the factory with 260 psi. Use a Fox Float air pump
to adjust the spring rate and preload of the TSS shock. Your shock will have a
sticker on it with the minimum, maximum and factory pressure settings.
Suggested TSS Pressures
Setting PSI
Minimum Setting 200
Factory Setting 260
Maximum Setting 400
To tune the TSS shock:
1. Take the weight off the shock by lifting the bike from under the engine or
tipping it on its side.
2. Remove the shock’s silver valve cap.
39
THE PERFECT FIT
3. Thread the pump onto the shock’s valve-stem until the pump pressures up
and you are able to see the supplied pressure on the gauge.
NOTE
When the pump pressures up the shock instantly loses 20 psi from the volume
it takes to fill the pump hose. You will need to compensate for this when
checking pressures.
4. When finished, unthread the pump. You will hear a release of air when
unthreading the pump, but this will not affect the exact pressure you gave the
shock.
NOTE
When tuning your TSS shock, it is best to add or subtract air pressure in
increments of 25 psi at a time. Be very careful to not get snow or water inside
the valve stem; this can cause the shock to leak air.
5. For a more refined tuning method, you may use the TSS shock O-ring which
can be found on the outer shock body. The O-ring is designed to be a gauge
for measuring the amount of shock travel you are using when riding.
To measure the amount of shock travel:
1. Slide the O-ring down to it’s lowest point.
2. Ride the snow bike for approximately 10 minutes.
3. Stop the bike and measure the amount the O-ring has moved. To measure
O-ring movement, measure the distance between the O-ring’s starting point
(when moved down to it’s lowest point) and the O-ring’s current location
(after a 10 minute ride).
The O-ring movement equals the amount of TSS shock travel. The TSS
shock has a max travel distance of 1.5” to bottom out. It is recommended that
the targeted amount of shock travel be about 1-1/8” of stroke.
4. Tune the TSS shock in increments of 25 psi to reach the targeted amount of
shock travel (1-1/8”) and accomplish perfect calibration.
NOTE
Each time you make a pressure adjustment (of 25 psi), slide the O-ring back
down to its lowest point and ride for approximately 10 minutes before
rechecking your shock travel distance.

PRE-RIDE INSPECTION
BEFORE STARTING THE ENGINE
Before starting the engine, reference your host bikes owner’s manual for engine
starting process and safety warnings.
WARNING
Operating the vehicle with worn, damaged, or malfunctioning components
could result in serious injury or death. Never start the engine without checking
all vehicle components to be sure of proper operation.
READ AND UNDERSTAND YOUR OWNER'S
MANUAL
Read your Timbersled owner's manual, as well as your host bike’s owner’s
manual, completely and refer to it often. The manual is your guide to safe and
enjoyable experience.
STEERING SYSTEM
WARNING
Ice and snow build-up may interfere with the steering of your snow bike,
resulting in serious injury or death. Keep the vehicle free of snow and ice.
Before driving, manually turn the ski to the left and right to be sure ice and snow
are not interfering with full left and right steering. If difficulty is encountered,
remove ice and snow build-up that may be obstructing the steering linkage or
front ski and skags.
Ensure fork clamps, spindle and ski bolts, and front axle bolt are torqued
properly.
43
PRE-RIDE INSPECTION
BRAKES
Always check the following items for proper operation before starting the engine.
BRAKE LEVER TRAVEL
Squeeze the brake lever. It should move no closer to the handgrip than 1/2 inch
(1.3 cm). A smaller distance indicates low brake fluid level or air in the hydraulic
system. Your dealer can assist.
LEVER FEEL
If the brake lever feels “spongy” when squeezed, check the brake fluid level and
condition.
WARNING
Continued use of “spongy” brakes may cause a complete loss of brakes, which
could result in serious injury or death. Always have the brakes serviced at the
first sign of sponginess.
NOTICE
To gain 100% braking performance, Timbersled recommends performing 20–
50 stop cycles of the Timbersled Brake System before first ride. Brake cycles
should be performed at a slow controlled speed in a flat, open environment.
Starting the snowbike and engaging it into gear, allow the track to spin 3–5 full
rotations. Apply moderate pressure to the brake until the track is completely
stopped and is no longer spinning. Repeat as necessary.
TRACK
Track damage or failure caused by operation on ice or poor lubrication
conditions voids the track warranty.
WARNING
Operating the snow bike with a damaged track increases the possibility of track
failure, which could cause loss of control resulting in serious injury or death.
Always inspect the track for damage before using the vehicle.
CAUTION
Use of traction products such as studs increases the possibility of track
damage and/or failure. Driving at high speeds for extended periods of time in
marginal lubrication could severely damage track rods, break track edges, and
cause other track damage. Examples of marginal lubrication would include
frozen bodies of water without snow cover, icy trails, and no-snow conditions.

TRACK WARM-UP
WARNING
A loose track or flying debris could cause serious injury or death. Stand clear of
the front of the snow bike and the moving track. Never hold the snow bike off
the ground or stand behind it while warming up the track. Do not use excessive
throttle during warm-up or when the track is free-hanging. Use a stable rear
support.
WARNING
Use of traction products such as studs, ice growsers, etc. will increase the
possibility of track damage and/or failure. This could cause loss of control,
resulting in serious injury or death. Always inspect for track damage before
operating the snow bike.
Follow these steps to ensure proper warm-up of the engine, drive train and
track.
1. Use an appropriate stand to securely support the rear of the snow bike. The
track should be about 4 inches (10 cm) off the ground.
2. Start the engine and allow it to warm up two to three minutes.
3. Engage the throttle abruptly and allow the track to rotate several revolutions.
TIP
It will take longer to warm up the track sufficiently during colder outdoor
temperatures.
4. Release the throttle, apply the brakes, shut off the engine and lower the
snow bike to the ground.
5. Grasp the ski by the front loop and move it from side to side to loosen snow
and ice.
SLIDE RAIL AND TRACK COOLING
NOTICE
Inadequate cooling and lubrication will lead to overheating of the slide rail and
track, resulting in premature wear and failure. Reduce speeds and frequently
drive into fresh snow to allow adequate cooling and polishing of the slide rail
and track surfaces. Avoid operating on ice, hard-packed surfaces or roads.

HOST BIKE MAINTENANCE
For host bike maintenance procedures and recommendations, refer to your host
bike’s owner’s manual. The maintenance information found in the manual only
applies to the Timbersled Snow Bike system.
TIMBERSLED RECOMMENDED MAINTENANCE
PROGRAM
Always follow recommended regular maintenance and perform service checks
as outlined in this manual. Record maintenance and service in the Maintenance
Log.
The recommended maintenance schedule on your vehicle calls for service and
maintenance inspections at 150 miles (240 km), 500 miles (800 km) and 1000
miles (1600 km). These inspections should be performed by a qualified service
technician. For continued optimum performance and component life, continue
maintenance checks at 1000 mile (1600 km) intervals.
All necessary replacement parts and labor incurred, with the exception of
authorized warranty repairs, become the responsibility of the registered owner.
If, during the course of the warranty period, part failures occur as a result of
owner neglect in performing recommended regular maintenance, the cost of
repairs are the responsibility of the owner.
Personal safety is critical when attempting to service or make adjustments to
your vehicle. If you're not familiar with safe service or adjustment procedures
and the use of tools, or if you don't feel comfortable performing these tasks
yourself, your authorized Timbersled dealer can provide any needed service.
NOTICE
Hot components can cause damage to plastic. Always make sure the exhaust
system and engine have cooled before tipping the vehicle on its side for
service or inspection.
NOTE
Timbersled recommends changing the oil in your host bike more frequently
that stated in the host bike’s owners manual.

MAINTENANCE
LUBRICATION
CHAIN LUBRICATION
Lubricate the chains every 8 to 10 hours of operation. We have found that the
use of Maxima Chain Wax for O- ring chains works best. It is recommended to
lift the track off the ground. Start the bike and put it into first gear and let the
clutch out allowing the drive system to spin. Slowly spray lube directly onto the
chain rollers and O-rings, soaking the chain. This will allow good penetration into
the moving chain parts.
TRACK LUBRICATION
The slide rail needs snow for lubrication. Excessive wear indicates insufficient
lubrication. A new rail slide can cause faster heat build-up in limited lubrication,
resulting in excessive wear.
WARNING
Operating with insufficient lubrication between the rail slide and track guide
clips can cause track failure, loss of vehicle control and loss of braking ability,
which can result in serious injury or death. Avoid operating for extended
periods on ice and other surfaces that have little or no snow for lubrication.
If excessive rail slide wear occurs due to poor snow conditions, additional
scratchers are available specifically designed for your model. Your dealer can
provide more information.
Track damage or failure caused by operation on ice or under other poor
lubrication conditions will void the track warranty.
EXHAUST SYSTEM
For exhaust system inspection procedures, see your host bike’s owner’s
manual.
CAUTION
Hot exhaust system parts can cause burns. Allow adequate time for the
exhaust system to cool. Never perform this procedure with the engine running.
52
MAINTENANCE
SUSPENSION
SUSPENSION MAINTENANCE
The following procedures should be performed regularly to properly maintain the
suspension of your snow bike.
1. Track tension and alignment adjustment may be required if the track starts to
skip on the drivers or if the rail slides are wearing too quickly. For more
information on track tension and alignment refer to the Track Maintenance
section (page 63).
2. Inspect rail slides regularly for wear and replace them if they have thin spots.
Rail slide wear can be prevented by making sure snow is spraying on them
when riding on the trail. It is recommended to install ice scratchers on the
rails if frequently riding on hard pack snow conditions. The rails are pre
drilled for this. Ice Scratchers and rail slides can be purchased through
Timbersled or most snow bike shops. For more information on rail slide
inspection and wear see the Rail Slide Wear section (page 72).
NOTE
Replacement rail slides are the same profile as late model Timbersled snow
bikes.
3. Timbersled RIOT models’ rear suspension arm is equipped with grease
fittings. The suspension comes with assembly grease on the bushings that
should last until the first maintenance period. Lubricate as necessary and at
the maintenance intervals indicated on the Periodic Maintenance chart (page
50).
53
MAINTENANCE
BRAKES
HYDRAULIC BRAKE INSPECTION
Inspect the brake lever reserve before each use of the snow bike. See page 44.
Brake pads must be replaced when the brake pad material becomes thinner
than 1/16 inch (1.5 mm). A kit is available for replacing brake pads. Your
Timbersled dealer can assist.
WARNING
Brake failure during operation can result in serious injury or death. Properly
functioning brakes are vital to your safety. Be sure the brake pads do not drag
on the disc and that brake lever travel is not excessive. Always replace brake
pads when the brake pad material becomes thinner than 1/16 inch (1.5 mm).

EXCESSIVE LEVER TRAVEL
Hydraulic brakes are self-adjusting, but if excessive brake pad clearance

TIP
The lightweight brake discs have vent holes that may cause a high-pitched
sound during operation.
54
MAINTENANCE
BRAKE FLUID
The brake fluid level can be seen through a plastic sight glass in the brake
reservoir. If the fluid is sufficient, the sight glass will be black. If the sight glass is
any color other than black, add brake fluid.
Replace brake fluid at least every two years with DOT 4 high temperature brake
fluid, or an equivalent product.
WARNING
After opening a bottle of brake fluid, always discard any unused portion. Never
store or use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly
absorbs moisture from the air. The moisture causes the boiling temperature of
the brake fluid to drop, which can lead to early brake fade and the possibility of
accident or serious injury.
WARNING
Keep the master cylinder cover free of dirt and debris. The vent slits allow for
diaphragm movement, and if they become plugged, movement of brake fluid
below the diaphragm may be restricted, altering brake function.
NOTICE
Brake fluid will damage labels, paint and some plastics. Always wipe up spills
immediately.
BLEEDING THE HYDRAULIC BRAKE SYSTEM
Air in the hydraulic brake system will cause spongy brake lever action. If the
brakes feel spongy, bleed the system before operating the snow bike.
WARNING
Operating the vehicle with a spongy brake lever can result in loss of brakes,
which could cause an accident and lead to serious injury or death. Never
operate the vehicle with a spongy-feeling brake lever.
During the bleeding procedure, keep the brake handle as level as possible. The
reservoir must be in this position to minimize the possibility of air entering the
system through the reservoir vent.
55
MAINTENANCE
1. Remove the brake master cylinder reservoir cover and gasket.
2. Fill the master cylinder reservoir to between the MIN and MAX marks or 1/4-
5/16 inch (.6-.8 cm) below the lip of the reservoir opening. Reinstall the
gasket and cover.
3. Slip a rubber tube over the ball of the bleeder valve and direct the flow of fluid
into an approved container.
4. Squeeze the brake lever a full stroke. Then unscrew the bleeder valve 3/4 of
a turn to release air.
5. Close the bleeder valve and release the brake lever.
6. Repeat steps 4–5 until fluid flows from the bleeder valve in a solid stream
free of air bubbles.
WARNING
Overfilling the master cylinder leaves no room for fluid expansion and may
cause the brakes to lock, resulting in serious injury or death. Always add brake
fluid to the fill line as recommended.
7. After bleeding is complete, refill the reservoir to the proper level.
8. Reinstall the gasket and cover.

DRIVE SYSTEM
DRIVE CHAIN TENSION
For long chain life and reliability, it is extremely important that you keep the drive
chain adjusted properly. Always check drive chain tension before riding.
IMPORTANT
TIMBERSLED SUSPENSION STRUT (TSS) MODELS: The TSS MUST be at
full extension and set to at least 200 PSI to measure and adjust drive chain
tension properly. To ensure the TSS is at full extension, remove all weight from
the shock. Inspecting and adjusting a chain without the suspension at full
extension will indicate a loose chain and lead to over-tensioning and excessive
chain stretch and wear.
56
MAINTENANCE
NOTE
The drive chain may loosen on the first ride due to initial chain stretch and
slider break-in. Retighten drive chain after the first few rides. If the problem
persists, your dealer can assist.
MEASURING DRIVE CHAIN TENSION
To measure drive chain tension before riding:
1. Ensure your snow bike is free of all snow and debris, positioned on a flat
even surface, and has no wheel kit positioned under it.
For Timbersled Suspension Strut (TSS) models, set TSS shock air
pressure to at least 200 PSI. Then ensure TSS suspension is at full
extension (i.e. no weight is on the shocks) by tipping the bike on its side or by
using an appropriate stand to lift the bike under its engine ensuring the track
is suspended off the ground.
2. Position a ruler behind or in front of the top chord of the drive chain, halfway
between the counter shaft sprocket and the jack shaft sprocket (this is where
drive chain displacement should be measured)
q. Steady the ruler so it does
not move as chain displacement is measured.
57
MAINTENANCE
3. Choose a single chain link pin close to the ruler to use as a reference point
for measuring chain displacement. Push down on the top chord of the chain
with one finger and line up the 1 inch mark on the ruler with the chosen chain
pin w
(see photo).
4. Then, without moving the ruler, push up on the top chord of the chain with
one finger in the same location and count the number of 1/8
th in. marks
between the 1 inch mark and the new position of the chosen chain pin
e.
If the chain is properly tensioned, there should be between 0.75 in. and 0.25
in. between the 1 inch mark (the position of the chosen chain pin when
pressed down) and the current position of the chosen chain pin (when
pressed up). This is the drive chain’s displacement measurement. If the drive
chain’s displacement measurement is less or more than 0.75 in. and 1.25 in.
the chain needs to be adjusted (see Adjusting Drive Chain Tension).
58
MAINTENANCE
ADJUSTING DRIVE CHAIN TENSION
To adjust drive chain tension, follow the steps below.
1. If the chain needs to be adjusted, loosen both 15 mm frame rail slide bolts
r
located on the right side of the Timbersled.
2. Next, loosen the 13 mm inner jam nut
y
on the inner frame tension adjuster
bolt t.
3. Adjust the tension adjuster bolt
r
in or out to achieve the correct chain
tension.
4. Re-torque the jam nut
y
to 25 Nm.
5. Re-torque the frame rail slide bolts
r
to 50 Nm.
6. Measure the drive chain’s displacement once again to ensure it is properly
adjusted.
If the chain is too tight and the frame is
difficult to compress, you may loosen
the front right-hand side panel bolt
u
and the front right-hand frame bolt
i
to
allow the frame to slide easier. Re-
torque both bolts to 60 Nm prior to
tensioning the chain.
59
MAINTENANCE
CHAIN CASE CHAIN TENSION
It is recommended that you measure the chain case chain tension each time the
chain is lubricated.
CAUTION
Do not over-tension the chain. Improper chain tension can cause excessive
wear to the chain and the tension roller bolt.
MEASURING CHAIN CASE CHAIN TENSION
To measure the chain case chain’s tension:
1. Remove the fasteners that hold the chain case cover on.
2. Position a ruler behind or in front of the right chord of the drive chain halfway
between the drive shaft sprocket
r
and the jack shaft sprocket
w
(this is
where the chain’s displacement should be measured). Position and steady
the ruler so it does not move as chain displacement is measured.
3. Choose a single chain link pin close to the ruler to use as a reference point
for measuring chain displacement. Push the chain’s right chord to the left
near the chosen link pin using 1 finger. Line up the 1 inch mark on the ruler
with the center of the chosen chain pin.
60
MAINTENANCE
4. Then, without moving the ruler, push the chain’s right chord to the right with
one finger in the same location and count the number of ⅟₈” marks between
the 1 inch mark and the new position of the chosen chain pin.
If the chain is properly tensioned, there should be between ½” and
3
between the 1 inch mark (the position of the chosen chain pin when pressed
to the left) and the current position of the chosen chain pin (when pressed to
the right). This is the chain case chain’s displacement measurement
q. If the
chain’s displacement measurement is less or more than ½” to
3 ”, the chain
tension needs to be adjusted (see Adjusting Chain Case Chain Tension).
ADJUSTING CHAIN CASE CHAIN TENSION
To adjust the chain case chain’s tension:
1. Loosen the tension roller bolt
e.
2. Adjust the chain tension as needed by pushing the roller bolt
e
towards the
chain to increase tension or away from the chain to lessen tension.
3. Then tighten the tension roller bolt
e
firmly once again.
4. Measure the chain case chain’s displacement
q
once more to ensure proper
adjustment.
CHAIN INSPECTION
IMPORTANT
Regular drive chain and chain case chain inspection is important. A broken
chain can cause host bike damage.
Chains need to be regularly inspected for signs of wear, damage and stretching.
A drive chain or chain case chain that has stretched 1% or more of it’s length is
worn out and will need to be replaced.
NOTE
A chain with 1000 miles or 75 hours of use will need to be replaced (see
Periodic Maintenance Interval Table on page 50).
To measure chain stretch, perform the following procedure:
61
MAINTENANCE
1. To determine whether the chain has stretched 1% or more, first ensure the
chain is taut along the area you plan to measure (a screw driver
w
is used to
keep the drive chain taught in the drive chain image below).
Timbersled RIOT and ARO
snow bikes are equipped with
520 drive and chain case
chains which have a pitch of ⁵∕
or 0.625” (A chain’s pitch is the
length of a single link which is
measured from the center of
one pin to the center of the next
pin q).
2. Mark out the number of links to measure (see the following table to find the
number of links to measure for the chain you are inspecting). To mark this
number of links, begin by marking the first pin
e
and counting forward the
same number of pins (number of pins counted should equal the number of
links to measure). Finish by marking the final pin
r. (see image with first and
last pin marked).

3. Then measure the counted number
of links by measuring from the
center of the first pin e
to the center
of the final pin
r. This measurement
should equal a length somewhere
within the acceptable length range
(as shown in the previous table).
4. If the length of the counted chain
links equals or exceeds the
expected length plus 1% (see table)
the chain is worn out and must be
replaced.
If the length of the chain links is less
than the expected length plus 1% (i.
e. the length is within the acceptable
length range), the chain does not
need to be replaced at this time.
TRACK MAINTENANCE
TRACK INSPECTION
1. Using a hoist, safely lift and support the rear of the snow bike off the ground.
2. Rotate the track by hand to check for damage.
3. Carefully examine the track along the entire length of each rod. Bend the
track to check for breakage.
4. Replace the track if any rod damage is found.
WARNING
Broken track rods can cause a rotating track to come off the snow bike, which
could cause serious injury or death. Never operate with a damaged track.
Never rotate a damaged track under power.
TRACK ALIGNMMENT
Proper track alignment is an essential factor in proper snow bike handling and in
preventing excessive wear to the track and rail slides (i.e hifax).
63
MAINTENANCE
INSPECTING TRACK ALIGNMENT
To inspect track alignment, follow the steps below.
1. With the rear of the bike off the ground and properly supported by a stand,
allow the bike to idle in gear for several revolutions to inspect whether the
track is running straight. Then shut off the engine. When the track is properly
aligned, the track clips
u
should run evenly along the hifax
q
(i.e. rail slides)
and the track should be centered on the suspension.
2. Measure the horizontal distance
s
between the hifax
q
(i.e. rail slides) and
the track edge
a
on both sides of the bike.
3. If the track is aligned properly, both sides should have approximately the
same distance measurement
s
between the hifax and the track edge.
If the track is running too far to one side, track alignment should be adjusted.
See the following section, Adjusting Track Alignment.
64
MAINTENANCE
ADJUSTING TRACK ALIGNMENT
To adjust track alignment, follow the steps below.
1. With the rear of the bike off the ground and properly supported by a stand,
loosen the axle bolt
e.
2. Loosen the adjustment bolt’s jam nut
r.
3. If the track is running too far to the left, tighten the left side of the track by
turning the tension adjustment bolt
t, on the left side of the bike, to the right
(approximately one-half turn).
If the track is running too far to the right, tighten the right side of the track by
turning the tension adjustment bolt
t, on the right side of the bike, to the
right (approximately one-half turn).
NOTE
The amount you should turn the adjustment bolt on either side of the bike will
depend on how far off center the track is running. Therefore it is suggested that
you turn the bolt one-half turn at a time, checking the alignment between each
half-turn adjustment to determine if additional adjustment is needed.
4. Re-tighten the adjustment bolt’s jam nut.
5. Then re-torque the axle bolt.
