The rear arm shock absorber setting or
springs influences the load carrying capa-
bility of the snowmobile and should be
adjusted for the weight and riding prefer-
ence of the operator.
! WARNING
Read and understand the following
information before handling shock
absorbers that contain highly pres-
surized nitrogen gas.
• Do not tamper with tor attempt to
open the cylinder assemblies.
• Do not subject the shock absorb-
ers to an open flame or other high
heat source. This may cause the
unit to explode due to excessive
gas pressure.
• Do not deform or damage the cyl-
inders in any way. Cylinder dam-
age will result in poor damping
performance.
• Do not dispose of a damaged or
worn out shock absorber your-
self. Take the shock absorber to a
Yamaha dealer for any service.
Adjusting Front Ski Shock
Springs
The front ski shock springs are individually
adjustable for the terrain conditions and
driving style of the operator. The spring
adjuster nut has been set at the factory so the
correct amount of threads are exposed
between the adjuster nut and the threaded
shock body as an initial setting. Additional
ski pressure can be obtained by tightening
the spring tension; ski pressure can be
decreased by relaxing spring tension.
NOTE: Equal adjustments should
be maintained on both sides of the
snowmobile.
Front ski shock spring pre-load adjust-
ment is accomplished by loosening the
adjuster nut locking collar (B) from the
adjuster nut (A) and using the Spring
Adjuster Tool from the tool kit, rotating
the adjuster nut in whichever direction is
desired. Tighten the locking collar
against the adjuster nut.

To adjust the damping, use the adjust-
ment lever located above the EVOL
chamber on the shock. There are three
settings that may be chosen 1, 2, or 3.
Adjusting Fox Air Shocks
NOTE: It is recommended to moni-
tor the air pressure in the air shocks
once every month.
NOTE: Adjusting air shocks may
be done by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Yamaha Snow-
mobile dealer for this service. This
service is at the discretion and
expense of the snowmobile owner.
The air shocks are individually adjustable
for the terrain conditions and driving style
of the operator. The shocks are preset at the
factory (see chart) as an initial setting;
however, it is possible to "fine tune" the
shocks to match the operator's weight, rid-
ing style, and terrain conditions.
NOTE: Adding air pressure will
increase the air spring force; reduc-
ing air pressure will decrease air
spring force.
