Refer to the Safety Precautions on page .
The service life of the drive chain is
dependent upon proper lubrication and
adjustment. Poor maintenance can cause
premature wear or damage to the drive
chain and sprockets.
The drive chain should be checked and
lubricated as part of the Pre-ride Inspection
(page ). Under severe usage, or when
the motorcycle is ridden in unusually dusty
or muddy areas, more frequent
maintenance will be necessary.
Inspection:
Turn the engine off, place the motorcycle
on its side stand and shift the
transmission into neutral.
Check 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:
Roll the motorcycle forward. Stop. Check
the drive chain slack. Repeat this
procedure several times. Drive chain

links are kinked and binding. Binding and
kinking can frequently be eliminated by
lubrication.
