rection (a). To loosen the drive

er drive chain slack will over-
load the engine as well as other
vital parts of the motorcycle and
can lead to chain slippage or
breakage. If the drive chain
slack is more than 25.0 mm
(0.98 in), the chain can damage
the frame, swingarm, and other
parts. To prevent this from oc-
6-23
