Drive Chain
(Refer to the Safety Precautions on page 55.)
The service life of the drive chain (1) 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, adjusted and
lubricated as part of the Pre-ride Inspection (page
46). Under severe usage, or when the motorcycle
is ridden in unusually dusty or muddy areas, more
frequent maintenance will be necessary.
Inspection
1. Turn the engine off, raise the rear wheel off the
ground by placing a support under the engine,
and shift the transmission into neutral.
2. 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:
20 – 30 mm (0.8 – 1.2 in)
3. Roll the motorcycle forward. Stop. Check the drive
chain slack. Repeat this procedure several times.
Drive chain slack should remain constant. If the
chain is slack only in certain sections, some links
are kinked and binding. Binding and kinking can
frequently be eliminated by lubrication.
NOTICE
Excessive chain slack may allow the drive chain to
damage the engine cases.
