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
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas.
1. The drive chain should be lubricat-
ed every 6 months. First, remove
all dirt and mud from the chain with
a brush or cloth. Then, spray any
of the many brands of spray-type
chain lubricant between both rows
of side plates and on all center roll-
ers.
2. To clean the chain thoroughly, re-
move it from the machine, dip it in
solvent, and clean out as much dirt
as possible. Then, take the chain
out of the solvent to dry it, and im-
mediately lubricate it to prevent it
from rusting.

a Yamaha dealer to replace it.
