NOTICE:
Improper
drive chain slack will overload
the engine as well as other vital
parts of the motorcycle and can
lead to chain slippage or break-
age. If distance A is more than
55.0 mm (2.17 in), the chain can
damage the frame, swingarm,
and other parts. To prevent this
from occurring, keep the drive
chain slack within the specified
limits.
