CHAIN SLACK INSPECTION
To check chain slack:
•
Stop the engine.
•
Place the vehicle on the stand.
•
Put the gearbox in neutral.
•
Check chain slack in the lower straight portion of chain.
The vertical movement of the chain midway between
the sprockets should be approximately 25 - 35 mm.
•
Wheel the motorcycle forward to check slack at various
sections of the chain. Slack should be the same
throughout one full turn of the wheel.
WARNING
If slack is greater at particular positions of the
chain, it means that some links are warped or
have seized. To prevent seizure, lubricate the
chain frequently; see
Chain slack must be adjusted whenever outside the
specified range of 25 - 35 mm, even when it is consistent at
all positions of the chain. See
WARNING
Exceeding slack in the chain may cause the
chain to rattle or knock, resulting in a worn
chain slider and guide.
Improper maintenance may lead to early wear
of the chain and/or sprocket damage.
Service the final drive more frequently when the
motorcycle is used in demanding conditions or
on dusty/muddy roads.
