Automatic clutch inspection
The scooter is equipped with an automatic clutch
and variable ratio belt drive transmission. The
engagement of the clutch is governed by engine
RMPS and centrifugal mechanism located in the
clutch.
To insure proper performance and long lifespan of
the clutch, it is essentiall that the clutch engages
smoothly and gradually. Two inspection checks must
be performed to thoroughly check the operation of
the drivetrain. Follow the procedures listed.
