FRONT SUSPENSION Compression Damping Adjustable Shocks
Snowmobiles equipped with the Indy Select or Ryde FX shocks allow the driver to make adjustments to the compression valving by turning the screw located near the base of the shock
Adjustment
Locate the adjustment screw near the base of the shockNOTE: This adjustment is easiest to make with the machine tipped on its sideWARNING
Be sure to shut off the fuel supply before tipping the machine to prevent fuel spillage and flooding of the carburetorsBy turning the screw clockwise (a small screwdriver or dime work well), the compression valving is increased, stiffening the rideTo soften the ride, reduce the compression by turning the screw counter-clockwiseA great deal of ride performance is accomplished with mere 12 to turnsThere are approximately full turns of adjustment available
