6-26Cable inspection and lubrication 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 especially necessary when riding in dusty
areas.
1. Use Yamaha Chain and Cable Lube or any brands of
spray-type chain lubricant. First, remove all dirt and mud
from the chain with a brush or cloth, then spray lubricant
between both rows of side plates and on all center
rollers. The chain should be lubricated every 500 km
(300 mi).
2. To clean the chain, remove it from the machine, dip it
in solvent, and clean out as much dirt as possible. Take
the chain out of the solvent and dry it. Immediately
lubricate the chain to prevent it from rusting.Damage to the outer housing of cables may allow
internal rusting and cause interfere with cable
movement. Replace damaged cables as soon as
possible to prevent unsafe conditions.
Lubricate the inner cable and the cable end. If it does not
operate smoothly, ask a Yamaha dealer to replace them.
RECOMMENDED LUBRICANT:
Engine oil SAE 20W50
