DRIVE CHAIN
Regular cleaning, lubrication, and proper adjustment
will help to extend the service life of the drive chain.
•
Take care to prevent catching your fingers be-
tween the chain and sprocket.
Inspection
1. Turn the engine off, raise the rear wheel off the
ground by placing the optional workstand or equiva-
lent support under the engine and shift the trans-
mission into neutral.
2. Check slack in the drive chain midway between the
sprockets, above the swingarm. Drive chain slack
should allow 1—1-3/8 in (25—35 mm) of vertical
movement.
NOTE:
•
Excessive chain slack may allow the drive chain to
damage the engine cases.
(1) DRIVE SPROCKET
(2) DRIVEN SPROCKET
(3) DRIVE CHAIN SLACK
If the chain is found to be slack in one segment of its
length and taut in another, this indicates that some of
the links are either worn, kinked or binding. Kinking and
binding can frequently be eliminated by thorough clean-
ing and lubrication. If the drive chain requires adjust-
ment, the procedure is as follows:
Rear Brake Pads
Inspect the pads visually from the rear side of the
caliper to determine the pad wear. If either pad is worn
anywhere to a thickness of 0.04 in (1 mm), both pads
must be replaced.

Other Checks
Make sure there are no fluid leaks. Check for deteriora-
tion or cracks in the hoses and fittings.
