CHECKING THE DRIVE CHAIN
4-69
CAUTION
This motorcycle has a drive chain with
small rubber O-rings  between the drive
chain side plates. Never use high-pressure
water or air, steam, gasoline, certain sol-
vents (e.g., benzine), or a coarse brush to
clean the drive chain. High-pressure met-
hods could force dirt or water into the drive
chain’s internals, and solvents will deterio-
rate 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.
