Lubrication and Cleaning:
Lubricate every 1,000 km (600 miles) or
sooner if chain appears dry.
The drive chain on this motorcycle is
equipped with small O-rings between the
link plates. These O-rings retain grease
inside the chain to improve its service life.
The O-rings in this chain can be damaged
by steam cleaning, high pressure washers,
and certain solvents. Clean the side surfaces
of the chain with a dry cloth. Do not brush
the rubber O-rings. Brushing will damage
them. Wipe dry and lubricate only with SAE
80 or 90 gear oil. Commercial chain lubri-
cants may contain solvents which could
damage the rubber O-rings.
