On models with QS3 shocks, use the
adjustment lever located above the
remote reservoir on the shock to adjust
the damping between settings 1, 2, or 3.
Setting #3 is the stiffest and most con-
trolled position.
QSL Rear Arm Shock
The rear arm shock (QSL) has an adjust-
ment lever on the shock to adjust the
damping. There are three settings that
may be chosen: 1, 2, or 3.
Choose from three specifically calibrated
ride control settings, with the 3rd posi-
tion calibrated specifically for technical
mountain riding, allowing increased
climbing capabilities and limited transfer
of the rear suspension.
The third setting should only be used
when riding in the back country. This set-
ting is not designed for trail riding.
Adjusting Skid Frame
Front Arm
The skid frame front arm shock spring
tension and the limiter straps are adjust-
able. However, Yamaha recommends that
the shock spring be maintained at the fac-
tory preset of 3.2-6.4 mm (1/8-1/4 in.)
preload. Tightening the skid frame front
arm shock spring may cause improper bal-
ance and may ruin the handling features of
the snowmobile.

The length adjustment of the front arm
limiter straps determines the weight dis-
tribution between the front of the skid
frame and the skis. Tightening the limiter
strap (shortening the strap) will pull up
on the front of the skid frame and will
increase ski pressure. Loosening the lim-
iter strap (lengthening the strap) lowers
the front of the skid frame and decreases
ski pressure.
When customizing the amount of ski
pressure, be sure to adjust both straps
equally and do not over-adjust the limiter
straps to adversely affect steering and
operator control of the snowmobile.
Some experimentation may be required
0745-159
until the proper adjustment for the opera-
tor's individual style is obtained.
NOTE: If the limiter strap is adjusted,
it is highly recommended that a mini-
mum of 3.2 mm (1/8 in.) preload be
maintained on the shock spring.
Do not adjust the front arm limiter
straps to a point at which steering
and operator control of the snowmo-
bile are adversely affected.
Adjusting Rear Spring
Preload
Proper adjustment of rear spring preload
is necessary to get the most desirable
0755-100
ride. The chart is designed to help in set-
ting up rear spring preload; however, rid-
ing style is the single greatest factor in
determining rear spring requirements.
