If the drive chain wear exceeds the service limit, re-
place the chain or an unsafe riding condition may
result. A chain that breaks or jumps off the sprock-
ets could snag on the engine sprocket or lock the
rear wheel, severely damaging the motorcycle and
causing it to go out of control.
For safety, use only the standard chain. It is an end-
less type and should not be cut for installation.

Drive Chain Lubrication
If a special lubricant is not available, a heavy oil such as
SAE 90 is preferred to a lighter oil because it will stay on
the chain longer and provide better lubrication.
If the chain appears especially dirty, clean it before lubri-
The O-rings between the side plates seal in the lu-
bricant between the pin and the bushing. To avoid
damaging the O-rings and resultant loss of lubri-
cant, observe the following rules:
Use only kerosene or diesel oil for cleaning an O
-ring drive chain.
Any other cleaning solution such as gasoline
or trichloroethylene will cause deterioration and
swelling of the O-ring.
Blow the chain dry with compressed air immedi-
ately after cleaning.
Complete cleaning and drying the chain within 10
Apply oil to the sides of the rollers so that oil will penetrate
to the rollers and bushings. Apply the oil to the O-rings so
that the O-rings will be coated with oil.
Wipe off any excess oil.
