ADJUSTMENTS
Rear Axle Drive Chain
To adjust the rear axle drive chain, loosen the rearmost eccentric locking
bolts and rotate using the same method as outlined for the front chain
adjustment. Total slack for the rear chain should be adjusted to 3/8"-1/2"
(9-13 mm) at the tightest point in the chain.
Optional Suspension Springs
Although the suspension has the capability of providing the best ride
possible, the following accessory springs are available to better suit
individual riding preferences.
NOTE:
Optional springs may be a different color than standard springs.
Springs may be painted to a desired color using Polaris touch-up
paint, available through Polaris dealers.
