adjustment.

temperature, shift the transmission into neutral and
place the motorcycle in the upright position.

Drive Chain

(Refer to "Maintenance Precautions" on page 42.)
Drive chain service life depends upon proper
lubrication and adjustment. Poor maintenance can
cause premature wear or damage to the drive chain
and sprockets.
The drive chain should be inspected and lubricated as
part of the Pre-ride Inspection (page 32) and its
maintenance performed as specified in the
Maintenance Schedule (page 40). Under severe riding
conditions, or when the motorcycle is ridden in
unusually dusty or muddy areas, more frequent
servicing will be necessary.
Inspection
1. Turn the engine off, raise the rear wheel off the
ground by placing a support block under the engine
and shift the transmission into neutral.
2. Check the drive chain (1) slack in the lower drive
chain run midway between the sprockets.
Drive chain slack should be adjusted to allow
the following vertical movement by hand:
20 – 30 mm (0.8 – 1.2 in).
