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 on-
ly kerosene to clean the drive chain. Wipe the
drive chain dry and thoroughly lubricate it with
engine oil or chain lubricant that is suitable for
O-ring chains. Do not use any other lubricants
on the drive chain since they may contain sol-
vents that could damage the O-rings.
Recommended lubricant
Engine oil or chain lubricant
suitable for O-ring chains
