NOTICE
Improper drive chain slack will overload the
engine as well as other vital parts of the mo-
torcycle and can lead to chain slippage or
breakage. If the drive chain slack is more
than the specified limit, the chain can dam-
age the frame, swingarm, and other parts. To
prevent this from occurring, keep the drive
chain slack within the specified limits.
