EAI40601Drive 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.

EAJ50002Troubleshooting
Although Yamaha motorcycles receive a
rigid inspection before shipment from the
factory, trouble may occur during opera-
tion. If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership have
the tools, experience, and know-how to
properly service your motorcycle. Use only
genuine Yamaha parts on your motorcycle.
Imitation parts may look like Yamaha parts,
but they are often inferior. Consequently,
they have a shorter service life and can
lead to expensive repair bills.
