ADJUSTING THE DRIVE CHAIN SLACK
The drive chain slack must be checked at the
tightest point on the chain.
A drive chain that is too tight will overload
the engine and other vital parts, and one that
is too loose can skip and damage the swin-
garm or cause an accident. Therefore, keep
the drive chain slack within the specified
limits.
1. Stand the motorcycle on a level surface.
Securely support the motorcycle so that
there is no danger of it falling over.
Place the motorcycle on a suitable stand so that
the rear wheel is elevated.
2. Spin the rear wheel several times and find
the tightest position of drive chain.
