est position.
Inspect the drive chain when the motorcy-
cle is on the centerstand. Check the slack at
the position shown in the illustration.
Normal slack is approximately 20~30 mm.
If the slack exceeds 30 mm, adjust it.

Drive chain lubrication
The chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out quick-
ly. Therefore, the chain must be serviced
regularly. This service is especially neces-
sary when riding in dusty areas.
1. Use any of the many brands of chain
lubricant. First, remove all dirt and
mud from the chain with a brush or
cloth, then apply lubricant between
both rows of side plates and on all
center rollers. The chain should be lu-
bricated every 500 km.
2. If the chain is too dirty or rusty, take
the motorcycle for repair.
