When adjusting, be sure springs on both the left and
right sides of the machine are at the same adjust-
ment.
For the best ride the spring preload should be as low
;as possible. Set the preload to use the full travel of
the ski shock with occasional light bottoming. To de-
termine if your machine is using full travel, push the
shock jounce bumper down as far as it will go on the
shock rod and test ride the machine.
The bumper will move up on the rod in direct relation
to the amount of travel. For example, if the shock
travel is full, the bumper will be seated at the top of
the shock.
The purpose of the shock coil spring is to control ride
height. The purpose of shock valving is to control
damping. If you find that in order to obtain the desired ride effect the spring preload
is at its maximum, consider removing the existing spring and install the next highest
rate spring.
D Remove the existing spring and install the next highest rate spring, or
D Reduce the preload on the existing spring and change the shock valving to
obtain the desired effect.
WARNING
Changing shock valving on Foxt shocks requires special tools and a sound
knowledge of mechanical theory, tool use, and shop procedures in order to perform
the work safely and correctly. Shocks contain high pressure nitrogen gas. Ex-
treme caution should be observed when handling and working with high pressure
service equipment. This work should be performed by a Polaris dealer.
Always verify ski alignment before making adjustments to the IFS. See page 98
to check alignment. If the skis are misaligned, we recommend that your dealer cor-
rect this, as the camber adjustment may also be affected.
