Front Suspension Setup and Adjustments

Spring pre--load is one of the adjustment options which affects
ride. Preload is the amount of pressure at which the spring is
held. The longer the installed length of the spring, the less the
amount of pre-load; the shorter the installed length of the spring,
the more the amount of pre-load. An increase in IFS shock
spring pre-load will result in an increase in ski pressure.
To adjust front spring pre--load on threaded adjust models, grasp
the spring and turn in a clockwise direction (as viewed from the
top of the shock) to increase the pre--load. Turn in a counter-
clockwise direction to decrease pre--load.(illustration 1)
In the illustration 2, high pre--load and low pre--load positions are
depicted.
When adjusting, be sure springs on both the left and right sides
of the machine are at the same adjustment.
CAUTION:
Increasing IFS spring pre--load too far can result in shock and
bulkhead damage due to "coil binding".
To determine 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.(See Illustration 3)

SPRING RATE

The correct spring rate will allow full travel of the shock with oc-
casional LIGHT bottoming.
If full travel is not being used you can:
S
Decrease clicker position (if applicable)
S Install a lighter spring rate
S
Revalve shock (if applicable)
If hard bottoming occurs:
S
Increase clicker position (if applicable)
S Install a heavier spring rate
S Revalve shock (if applicable)
