USER NOTICE AND DISCLAIMER

The YETI SnowMX Dirt-To-Snow bike conversion
System is designed to provide exceptional traction
and floatation in all winter conditions.

This document holds important information
regarding driving a motorcycle equipped with the
YETI SnowMX System. It is mandatory that every
user takes the time to carefully read, understand
and then consult this reference manual and user
guide as well as the motorcycle owner's manual as
needed. When purchasing either a new or used
Conversion System, the user must obtain all
documentation related to the System, including

manuals and guides related to the motorcycle on
which the System is installed. If need be, contact
the YETI products dealer nearest to you to obtain
any additional information. You may also consult
the Yeti Web site at www.yetisnowmx.ca and
contact our technical support by email at
[e-mail].

YETI believes that there are certain risks related to
the installation and use of the System. Our
experience shows that the System is safe.
However, the user must be aware of the risks
related with driving a motorcycle with the
particularities of this type of System. The
motorcycle rider must, at all times, respect all
applicable laws and regulations, the indications of
the System manufacturer and the indications from
the motorcycle manufacturer fixed by law, namely
when age restrictions exist and motorcycle base
equipment is required (headlights, flashers and
brake lights, rear view mirror, etc.). The user must
always wear adequate safety equipment, such as
a helmet, safety glasses (or visor), protective
clothing, boots and gloves. It is understood that

driving while impaired or intoxicated presents a
danger for the motorcycle user and others and is
against the law.

The System consists of many moving parts,
including transmission wheels. If an object lodges
itself or becomes jammed into the System and
blocks the track, it is mandatory to stop the engine
and the vehicle and apply the security brake
before removing said object. By avoiding to do so,
the user exposes himself to sudden movement of
the motorcycle or to breakage of a part or
component coming from the System, which could
cause severe injuries. It is also very important to
wear full length clothing and always avoid hanging
or stringy accessories.

Driving a motorcycle equipped with such a System
requires particular precautions and a knowledge of
proper driving techniques of such vehicles.

An evaluation by the user of the conditions and
terrain (state of the ground, grade of hill, density of
snow, etc.) is equally essential.

A motorcycle equipped with a System cannot
compete and/or be used to perform stunts,
acrobatics or other exploits, as these could result in
loss of control or severe injuries.

Insufficient knowledge of a motorcycle during down
hill riding, climbs and crossing of obstacles and
turns can result in tipping or roll over, and can
cause severe injuries.

Carrying a passenger, a load or attaching a tow can
cause the motorcycle to be less stable, and affect
usability. Unless otherwise prescribed by law and
by the motorcycle manufacturer, you must not carry
a passenger, loads or tow any objects.

The installation of a System:

• Increases ground clearance.

• Changes the center of gravity.

• Increases motorcycle length, width and weight.

• Reduces ground pressure.
These parameters will effectively change driving

characteristics of a motorcycle equipped with the
System.

Consequently, it is highly recommended that the

user adapt his driving style to the new
characteristics mentioned above. The rider must

always use caution when he crosses obstacles,
circulates through narrow paths, meets vehicles
coming in the opposing direction, etc.

As it was designed, the System will considerably
reduce the motorcycle top speed and can falsify
the speedometer. Generally, the System
transmission wheel diameter is less than that of the
tire. Therefore, the vehicle speed will be less than
that actually displayed. Whether the motorcycle is
equipped or not with the System, users must
always adapt the speed to actual driving
conditions. Users must never exceed speed limits
or drive faster than their capacities allow.
Excessive speed remains one of the main causes
of severe motorcycle accidents.

Camso is proud to offer dirt-to-snow motorcycle

conversion kits within its wide range of products.
Motorcycle Conversion Systems are not only
reliable, but safe. However, there are risks inherent
to riding a motorcycle equipped with the System. It
is therefore very important that the rider familiarize
himself with the proper riding techniques of a
motorcycle equipped with a System. The rider must
also adapt his riding to his experience level, and
continually evaluate operating conditions and
terrain to safely and efficiently make the best of the
YETI SnowMX motorcycle Conversion System.

WARNING

Riding a bike equipped with a Conversion System
differs from riding a two-wheeled bike. We
strongly recommend following the safety
guidelines provided below to prevent any
accident and/or serious malfunction that could
impact the rider, bike or Conversion System.



WARNING

Jumping with a bike equipped with a Conversion
System is not recommended. The System was
not designed for this type of operation. A bike
equipped with a System must never be used for
races, rallies, jumps, stunts, acrobatics or any
other extreme applications.



WARNING

When travelling in groups, riders following a
motorcycle equipped with a Conversion System
should be warned of dangerous objects that can
potentially be propelled by a tracked motorcycle.

OPERATING INSTRUCTIONS

HINTS AND TIPS

• Before going out on a ride, make sure to bring
along the following: 12, 13, 15, 16-mm sockets
and wrenches; 3, 5, and 6-mm Allen keys; an ax,
a shovel, a tow cable, a container of fuel, a
screwdriver type pry bar and an adjustable
wrench.

• Generally, the slower you go, the better the
traction will be.

• On excursions on unknown or remote terrain,
make sure to have with you a cellular or satellite
phone, a first aid kit and spare parts.

• When riding off trails, always be cautious of
potential hidden obstacles.

• In deep snow, do not intentionally spin the track
(track spins while bike remains stationary). This
could cause the bike to get stuck.

BREAK-IN PERIOD

CAUTION: A break-in period is necessary to allow
system components to settle and adjust to each other.

During the break-in period (8 hours or 160 km),
follow these recommendations:

• A GOOD break-in period must be done in a
lubricated environment such as a groomed trail
or soft snow.

• A BAD break-in period can generate smoke,
odors of burned rubber or plastic as well as
plastic deposits on track clips.

CAUTION: Non-compliance with the usage
recommendations can lead to a warranty claim refusal.

CAUTION: The owner / rider is responsible for
following the recommended scheduled maintenance
described in this manual.

CAUTION: Reduce your speed at all times; a
Conversion System installed on a motorcycle does
not have the same absorption capacity as a tire.

CAUTION: Do not operate at high speed or
continuously during extended periods, in dry
conditions such as icy trails, gravel, sand, or on
asphalt. This can cause extreme heat and can melt
down suspension / track components. If you detect
any smoke or odor of burned rubber / plastic, stop
the bike and let the track cool.

• During break-in, avoid operating in dry and
clean conditions such as icy trails, gravel,
asphalt or sand.

• Progressively increase bike speed and
acceleration.

• Pay attention to any abnormal noise or odor.

PRE-USE VERIFICATION

CAUTION: Before each ride make sure that the
System’s wheels and moving parts are free and that
they are not frozen or stuck on the frame.

CAUTION: Verify that the motorcycle’s air intake is
well adapted to weather conditions and is not
blocked by snow accumulation.

WARNING

The braking system is an important safety feature
of your YETI conversion system and must be
kept in good running order. It is the operator’s
responsibility to keep the Conversion System in
optimal running order. Failure to perform
maintenance or verifications before use of
Braking system could result in a loss of control
that could cause serious injury or death.

CHAIN INSTALLATION

Before installing the chain, the Bike mount should
be retracted as much as possible.

NOTE: For the next step, the bike should be raised

slightly so that the track is off the ground and
can be rotated.

• Insert chain (1) in upper opening at the front of
the system and feed it over jack shaft drive
sprocket (2). See

Figure 26

• Slowly rotate the YETI’s track to advance chain
links on the sprocket. Use a hook or magnet to
extract the chain out of the chassis through the
lower opening at the front. See Figure 27.

Figure 26.

CAUTION: The chain has the right length and does
not need to be shortened.

CAUTION: Observe direction of insertion for master
link locking clip.

CAUTION: Do not remove grease applied on master
link pins.

Figure 28

IMPORTANT: Chain adjustment is not done at
installation but will be done later. Leave play in the
chain to allow for other necessary adjustments to
be done first. Soft Strut adjustments impact chain
tension and therefore must be done before
adjusting chain tension.

NOTE: For further details on adjustments to be

performed on the Conversion System, see the
section entitled “Adjustments”.

Figure 27

• Install the provided chain on the engine sprocket
and join the ends using the master link. See
Figure 28.

BRAKE SYSTEM

IMPORTANT: YETI SnowMX recommends that
assembly, preparation and brake system setting
steps be performed by a YETI SnowMX dealer.

YETI SNOWMX USER MANUAL | 14



WARNING

Do not mix brake fluid types or grades. Some are
not compatible. Using the wrong type or mixing
incompatible fluids may cause loss or
inadequate breaking which may result in serious
injury or even death.

BRAKE LINE ROUTING

Two options are available to route the brake line:

- Route brake line along the chassis up to the

handlebars without removing any bodywork
component.

- Disassemble bodywork components to enable

easy routing of line and master-cylinder up to
handlebars.

No matter the chosen method, observe the
following recommendations:

• Follow existing line and cable routing.

• Re-use existing ties and clips to secure brake
line. Add more ties if needed.

• Do not position the brake line against sharp
edges in the Bike’s chassis.

• Maintain large radiuses in brake line to avoid
pinches.

• Keep line away from heat sources that can
damage it or overheat hydraulic fluid.

** 120SS model only **

BRAKE LINE HOOKUP & BLEEDING

IMPORTANT: To perform the following steps, use a
new bottle of brake fluid that meets the bike
manufacturer’s specifications.

• Insert the clear plastic tube at the end of the
medical syringe. These two items are included in
the common parts box shipped with your YETI.

• Open the brake caliper’s bleeder check valve
about ½ turn and push the other end of the
plastic tube on the bleeder valve.

• Position the new fluid bottle securely at
handlebar level. Submerge end of brake line in
brake fluid.

• Keep enough play in Brake line between
handlebars and chassis, to ensure that turning
radius is not reduced.

CAUTION: Presence of an important heat source
near the line, such as an exhaust pipe, or the

engine, can overheat the Braking system’s

hydraulic fluid and render it less effective. Route
the Brake line to bypass such heat sources.

** 129FR & 137MT models only **

• Install the master-cylinder on the handlebars at
the same position occupied by the original
braking system.

• Re-assemble all motorcycle components
removed during the Conversion’s System
installation and routing of the brake line (rear
frame section, exhaust, plastic side panels, tank,
seat, etc.). Observe the manufacturer’s torque
specifications when tightening bolts.

CAUTION: Be sure to apply the bike manufacturer
requirements at reassembly of components.

NOTE: There must not be any loop in the brake line.

Keep it in an uphill position during the next step.

IMPORTANT: In the next step, the brake line end
must be submerged continuously in fluid.

• Pull on the syringe to fill the line and brake
caliper.

• Once brake fluid has started filling the syringe,
give it a pull to fill it completely. Then close the
bleeder check valve on the brake caliper.

• Remove end of plastic tube from bleeder valve.

NOTE: Squeeze the new brake fluid contained in the

syringe back into the brake fluid bottle.

• Remove end of brake line from brake fluid bottle.
and keep it in an upward position.

WARNING

Apply the recommended torque to banjo bolt in
master cylinder. Inadequate tightening of banjo
bolt may cause loss or faulty breaking which may
result in serious injury or even death.

** 120SS model only **
IMPORTANT: During the next steps, keep the end

of the brake line in an upward position to avoid
formation of air pockets in your primed brake line.

• Remove banjo bolt and rubber grommet inserted
temporarily during front brake disassembly.

• Insert banjo bolt (1) in end of brake line (2)
making sure to install the copper crush washers
(3) against both sides of the brake line banjo
end. See Figure 29.

Figure 29

• Reconnect plastic tube to brake caliper bleeder
valve. Open bleeder valve about ½ turn.

IMPORTANT: In the next step, check fluid level in
master cylinder reservoir and keep it full at all
times.

• Pump the brake lever fully. Check for air bubbles
in the fluid leaving the braking system and going
in the syringe. When there are no more air
bubbles, close caliper bleeder valve.

• Tighten bleeder valve to 5 Nm (44 lb-in). Reinstall
rubber dust cap on bleeder valve.

• Fill master cylinder reservoir to the rim. Reinstall
reservoir cover and tighten cover screws
according to manufacturer’s recommendations.

IMPORTANT: It is important to OVER FILL the
reservoir before putting the cover back on to
prevent air from entering the braking system if you
happen to tip the bike upside down while riding.

BRAKING SYSTEM VALIDATION
Perform the following test after assembly and

bleeding of the braking system.

• Engage by hand banjo bolt - brake line - crush
washers assembly in the bike’s master cylinder.
Then tighten banjo bolt to the manufacturer’s
torque specifications.

• Cut the zip tie that was installed temporarily on
the brake lever during the front brake
disassembly.

• Remove the master cylinder cover.

BRAKE LINE BLEEDING (ALL MODELS)

• Top off master cylinder reservoir with the same
new fluid used to prime your brake line.

• SLOWLY wiggle front brake lever in small
increments of ¼ - ½ lever travel at first. Pull lever
until there are no more air bubbles in brake fluid.

• Pump the brake lever a few times and tie it in the
closed position during 24 hours.

NOTE: Use a zip tie if the master cylinder does not have

a brake lever lock.

- If the system maintains pressure after 24 hours,

it is bled correctly.

- If the lever is even more closed after 24 hours,
check for fluid leaks in the braking system. if a
leak is detected, disassemble the braking system
and repair the leak.

- If there are no leaks and the lever is abnormally
closed, re-bleed the braking system.

YETI SNOWMX USER MANUAL | 16

ADJUSTMENTS

CAUTION: Adjustment settings on your YETI must
be verified after first use on the bike. Soft Strut
setting, rubber track tension, Syncro belt tension
and chain tension must be re-checked. Incorrect
adjustments can decrease system performance and
produce premature wear on certain components.

SOFT STRUT - ADJUSTMENT

Adjustment of the Soft Strut has a direct impact on
the bike’s handling. Modifying the Strut adjustment
according to the changing snow conditions has a
radical effect on ski behavior.

• Place bike on ground, supported on ski skag and
rubber track.

Front Measurement Point (A): Measure distance
between top of rail slide and the ground, at 1.00”
(25mm) back of front shock lower mounting bolt.
Figure 30.

Back Measurement Point (B): Measure distance
between top of rail slide and the ground, at 1.00”
(25mm) back of back shock lower mounting bolt.
Figure 30.

• At the front measurement point (A), measure
distance (X) between the top of the rail slide and
the ground. See Figure 31.

Figure 31

• At the rear measurement point (B), measure
distance (Y) between the top of the rail slide and
the ground. See Figure 32.

Figure 30

Recommended setting: The rear measurement
must be 0.300 to 0.500” (7,6 to 12,7 mm) higher
than the front measurement with the suspension
on the ground.

Figure 32

• Calculate the difference between the rear and
front measurement points.

Rear (Y) - Front (X) = 0.3 to 0.5” (7,6 to 12,7 mm)

Reaction to Soft Strut adjustment:

- One complete counterclockwise

rotation of the
Soft Strut shortens it by 0.050” (1,27 mm). The
rear measurement (Y) will then increase 0.050”
per rotation.

- One complete clockwise

rotation of the Soft
Strut lengthens it by 0.050” (1,27 mm). The front
measurement (X) will then increase 0.050” per
rotation.

17 | YETI SNOWMX USER MANUAL

• Loosen the rod end lock nut (1). Adjust length of
rod end by rotating the Soft Strut (2) using a 31­mm wrench. See

Figure 33

NOTE: Each time Soft Strut adjustment is checked,

raise bike’s rear and lower it back down slowly.

Figure 33.

• Adjust length of Soft Strut until the rear
measurement point is 0.300 to 0.500'' higher
than the front measurement point.

• Once the Soft Strut adjustment is completed,
tighten the lock nut (1) back to 40 Nm [30 lb-ft].

An adjustment above 0.500” at the rear
measurement point:

- lowers ski pressure;

- shortens the bike’s virtual wheelbase;

- produces more skittish handling on trails;

- produces better handling at low speeds.

CAUTION: An adjustment above 0.750” at the rear
measurement point is not recommended. The bike
then becomes hard to handle and unpredictable.

SHOCK ABSORBER ADJUSTMENT

Two (2) shock absorber combination options are
available for YETI SnowMX 2020 models:

Option 1: ELKA Stage 3, front & rear
Option 2: ELKA Stage 5, front & rear

ELKA Stage 3

(front & rear option 1)

Spring preload and compression can be adjusted
on these shock absorber model.

Basic Tuning

An adjustment of under 0.300” or 0.000” (Flat)
at the rear measurement point produces:

- a better angle of attack for hill climbing;

- better handling in deep or powder snow;

- greater ski pressure;

- more stability at higher speeds.

An adjustment of between 0.300” and 0.500”
higher at the rear measurement point is:

- the recommended adjustment for all conditions;

- the best compromise suited for various uses
and snow conditions.

ELKA Stage 5

(front & rear option 2)

Spring preload, compression and rebound can be
adjusted on these shock absorber models.

Spring Preload

The shock absorbers are factory set for a 180-lbs
rider. Spring preload on shock absorbers can be
adjusted to take into account a rider’s weight and
riding style.

Proceed as follows:

• Loosen the spring preload adjustment ring
locking screw a few turns. Use a 3-mm Allen key.

• Rotate adjustment ring to raise or lower shock
absorber spring preload. Use the provided tool.

NOTE: Rotating ring clockwise lowers spring preload.
NOTE: Rotating ring counterclockwise raises spring

preload.

YETI SNOWMX USER MANUAL | 18

• Once adjustment is completed, tighten
adjustment ring locking screw.

IMPORTANT: Modification of Shock absorber
spring preload impacts Soft Strut adjustment. Soft
Strut adjustment must absolutely re-checked if the
shock absorber spring preload is modified.

CAUTION: Spring preload must be set at a level
sufficient to keep the spring seated solidly in place.
Damage to components could occur if spring
preload is too low.

CAUTION: Minimum front a-arm shock absorber
spring preload should result in a distance of not
less than 23mm between preload ring and start of
threaded portion of shock body. See Figure 34.

DRIVE CHAIN

IMPORTANT: Soft Strut adjustment must be
completed before adjusting the drive chain tension.

• Position the bike level on the ground

• Lift automatic chain tensioner (1) off the chain
and keep it up (e. g. with a zip tie) to avoid
adding tension to the chain during adjustment.
See Figure 35.

Figure 35

Figure 34

Compression and Rebound

Following the option chosen at purchase of your
YETI SnowMX, shock absorbers can be adjusted
in compression and rebound.

ELKA

Consult the ELKA owner’s manual provided with
your YETI for more details relative to compression
and rebound settings (if applicable).

• Loosen eccentric bolt nut (1) a little using the
special socket provided in your YETI SnowMX
parts kit. Figure 36.

• Loosen slightly, the two M8 bolts (2), and the
four M10 bolts (3-4) on each side of the Bike
Mount so that the Bike Mount assembly can
slide. Figure 36.

Figure 36

NOTE: Be careful to not loosen the two bolts (2) too

much; T-nuts could fall out and be lost.

• Rotate eccentric bolt (7) to adjust chain tension
as required. Use a 12-mm socket. Figure 37.

IMPORTANT: Remove all play in the chain without
over-tensioning it. The chain must be tensioned
before tightening Bike mount bolts and locking it in
place.

• Tighten in sequence: the eccentric bolt nut (1) to
61 Nm (45 lb-ft); the four M10 bolts (3-4) of the
Strut block to 41 Nm (30 lb-ft); and the two M8
bolts (2) at the front of the Bike Mount to 25 Nm
(18 lb-ft). See Figure 38.

Figure 39

• With your thumbs, apply pressure to the belt (1),
where the tension gauge (2) sits, toward the
tensioner pulley (3). See Figure 40.

Figure 40

• Recommended setting: Required belt tension
is 11 mm (7/16'') of play, which corresponds to
the width of the red tension gauge in the
tensioner mechanism. See Figure 41.

• Release the automatic chain tensioner back
onto the chain.

SYNCRODRIVE BELT

IMPORTANT: Verify belt tension after 1 or 2
kilometers, and 3 or 4 times on your first outing. If
you notice a significant change in belt tension, re­adjust tension.

Syncrodrive Belt Tension Verification

• Slide the red tension gauge (1), incorporated in
tensioner mechanism, to the outer edge of the
Syncrodrive belt. See Figure 39.

• Loosen tensioner pulley nut (1) ½ to ¾ turn. See
Figure 42.

IMPORTANT: Do not loosen tensioner pulley nut
(1) more than ½ to ¾ turn. If the nut is too loose
during the adjustment process, the belt tension
could increase when the nut is tightened back.

• Loosen lock nut (2) on Belt Tensioner adjusting
bolt. See Figure 42.

YETI SNOWMX USER MANUAL | 20

• Rotate Belt Tensioner adjusting bolt (3) to raise
or lower belt tension. See Figure 41.

Figure 42

• Tighten tensioner pulley nut (1) back to 55 Nm
(38 lb-ft) of torque. See Figure 42.

• Verify tension adjustment. Repeat previous
steps if tension is found insufficient.

TRACK TENSION

CAUTION: The two rear wheel assembly axle nuts
(1) must be loosened before adjusting Track
tension. See Figure 43.

Figure 43

• Rotate the right and left rear wheel axle
adjusting bolts (2) an equal number of turns,
clockwise or counterclockwise, to set the Track
to the recommended tension. See Figure 44.

Figure 44

CAUTION: Use a ruler to verify how long the
adjusting bolts are engaged in the axle. A
misaligned rear axle can cause premature wear of
suspension components.

• The table below shows the force applied and the
deflection which must/ occur when track tension
is correctly set. Refer also to Figure 45.

21 | YETI SNOWMX USER MANUAL

DEFLECTION = 19 mm

[¾ in.]

BASIC TUNING

• A higher rubber track tension reduces drive
“ratcheting”.

NOTE: Track tension set too high could cause

premature wear on system components.

• A lower rubber track tension provides better
traction, a smoother ride and better fuel
economy.

• Check Track tension at mid-point between the

two lower shock absorber mount shafts. Figure

45.

Figure 45

• Tighten the two rear wheel axle nuts (1) back to

55 Nm (38 lb-ft) of torque. Figure 42
