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.
1．Inspect initial engagement
Warm up the scooter to normal operating
temperature.
Remove the right frame side cover.
Connect an electric tachmeter to the connecting portion
of the magneto lead wire (black with red tracer).
Seated on the scooter with the scooter on level ground,
increase the engine RPMs slowly and note the RPM at
which the scooter begins to move forward.
Tachometer
Standard 2900r/min
tolerance ±300r/min
2．Clutch “LOCK-UP” inspection
Perform the inspection to determine if the clutch is
engaging fully and not slipping.
Warm the engine to normal operating temperatures.
Connect the electric tachomter to the magneto lead
wire.
Apply the rer brake as firm as possible.
Briefly open the throttle fully and note the maximum
engine RPMs sustained during the test cycle.
CAUTION:
Do not apply full power for more than 10 seconds or
damage to the clutch or engine may occur.
