MAINTENANCE
Drive Chain
Rear Drive Chain Slack
Check the amount of chain slack in three different locations by moving
the vehicle slightly forward to gain slack at the top side of the rear
chain. Measure the chain slack at the tightest of the three positions. At
this point the chain should have 3/16"-3/8" (5 mm - 10 mm) deflection.
Adjusting or operating the vehicle with improper rear drive chain slack can result
in severe damage to the transmission and drive components. Always make sure
the slack is within the stated specifications.
Use the following procedure if adjustment is required.
1. Remove the chain guard.
2. Loosen the chain guide.
3. Loosen the two eccentric
locking bolts.
4. Loosen the caliper mounting
bolt located on the left side
of the swing arm.
5. Insert a pin punch through
the sprocket hub and into the
eccentric housing.
