Drive Chain

(Refer to the Safety Precautions on page 41.)
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 33). 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, place the motorcycle on its side
stand, 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:
10 – 20 mm (0.4 – 0.8 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.

4. Inspect the sprocket teeth for possible wear or
damage. Replace if necessary.
If the drive chain or sprockets are excessively worn or
damaged, they should be replaced. Never use a new
chain with worn sprockets; rapid chain wear will result.
