LUBRICATING THE DRIVE CHAIN
The drive chain consists of many interacting
parts. If the drive chain is not maintained prop-
erly, it will wear out quickly. Therefore, the
drive chain should be serviced, especially
when the motorcycle is used in dusty areas.
This motorcycle has a drive chain with small
rubber O-rings between each side plate.
Steam cleaning, high-pressure washing, cer-
tain 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 engine oil or chain lubricant that is suit-
able 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.
Recommended lubricant
Engine oil or chain lubricant
suitable for O-ring chains
