3. Clean:

drive chain
a. Wipe the drive chain with a clean cloth.
b. Put the drive chain in kerosene and remove
any remaining dirt.

This motorcycle has a drive chain with small
rubber O-rings
1 between the drive chain
side plates. Never use high-pressure water
or air, steam, gasoline, certain solvents
(e.g., benzine), or a coarse brush to clean the
drive chain. High-pressure methods could
force dirt or water into the drive chain’s in-
ternals, and solvents will deteriorate the O-
rings. A coarse brush can also damage the
O-rings. Therefore, use only kerosene to
clean the drive chain. Don’t soak drive chain
in kerosine more them ten minutes. O-ring is
damage by kerosine.
