Adjusting Rear Spring Pre-
Load
Proper adjustment of rear spring pre-load
is necessary to get the most desirable
ride. The chart is designed to help in set-
ting up rear spring pre-load; however,
riding style is the single greatest factor in
determining rear spring requirements.


NOTE: These cam position set-
tings are suggestions only. Personal
riding style will greatly influence
cam position settings. Spend time to
determine setting preferences.
Rear spring pre-load adjustment is accom-
plished by rotating the adjusting cams.
Position 3 provides the stiffest ride, and
position 1 is for the light driver or slow-
speed trail riding. Position 2 is for the
average operator under normal conditions.
Always rotate the cam from the lighter
position to the heavier position.
CAUTION
Never force the adjustment cams
from the low position to the high
position. Cam damage may occur.
To rotate an adjusting cam, use the spark
plug wrench from the tool kit. Rotate the
wrench until the cam is in the desired
position. To stiffen the ride, rotate the cam
so as to raise the spring end. Make the
appropriate adjustment on the other cam.
Adjusting Skid Frame Rear
Arm Shock Spring
Proper adjustment of rear arm shock
absorber spring pre-load is necessary to
get the most desirable ride.
The rear arm shock spring is adjustable
for the terrain conditions and driving
style and weight of the operator. The
spring adjuster nut has been set at the fac-
Cam Position
tory so the correct amount of threads are
1
exposed between the adjuster nut and the
threaded shock body as an initial setting.

3 Rear spring pre-load adjustment 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.
