c. Remove the drive chain from the ker-
osine and completely dry it.
ACHTUNG:CAUTION:
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 internals,
and solvents will deteriorate the O-
rings. A coarse brush can also damage
the O-rings. Therefore, use only kero-
sine to clean the drive chain.
