CAUTION:
This motorcycle has a drive chain with small
rubber O-rings 1 between the drive chain
side plate. 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 kerosine to clean the
drive chain.
