The perimeter of the flywheel has gear teeth which are
engaged by the starter. Since the use of
this gearing is very intermittent, a little multipurpose
lubricating grease at
long intervals will provide
sufficient lubrication.
Motorcycle Gear Lubrication
While some models
of motorcycles recommend
special motorcycle oil, the transmission
of such vehicles often
use the heavier
grades of crankcase
oils. For low temperatures, SAE 30 or in some cases SAE 20W oil is
suggested and for higher temperatures SAE 40 or 50. The recommendations of
the manufacturer should
be noted and
followed both as to grade
and quantity of transmission oil. In at least one instance the transmission is combined with the
crankcase.
