Lubricating The Drive Chain; Checking And Adjusting The Steering Head - Yamaha YZF-R1 2020 Service Manual

LUBRICATING THE DRIVE CHAIN

The drive chain consists of many interacting
parts. If the drive chain is not maintained proper-
ly, it will wear out quickly. Therefore, the drive
chain should be serviced, especially when the
vehicle is used in dusty areas.
This vehicle has a drive chain with small rubber
O-rings between each side plate. Steam clean-
ing, high-pressure washing, certain solvents,
and the use of a coarse brush can damage
these O-rings. Therefore, use only kerosene to
clean the drive chain. Wipe the drive chain dry
and thoroughly lubricate it with chain lubricant
that is suitable for O-ring chains. Do not use any
other lubricants on the drive chain since they
may contain solvents that could damage the O-
rings.
