Drive Chain Lubrication - Yamaha FZR400 1988-1989 Service Manual

DRIVE CHAIN LUBRICATION/STEERING HEAD INSPECTION

DRIVE CHAIN LUBRICATION

The chain consists of many parts which work
against each other. If the chain is not maintained
properly, it will wear out rapidly, therefore, form
the habit of periodically servicing the chain. This
service is especially necessary when riding in
dusty conditions.
This motorcycle has a drive chain with small
rubber O-rings between the chain plates. Steam
cleaning, high-pressure washes, and certain sol-
vents can damage these O-rings. Use only kero-
sene to clean the drive chain. Wipe it dry, and
thoroughly lubricate it with SAE 30 - 5 0 W
motor oil. Do not use any other lubricants on
the drive chain. They may contain solvents that
could damage the O-rings.
Recommended Lubricant:
SAE 30 - 50 Motor Oil or Chain
Lubricants Suitable for "O-ring"
