AUTOMATIC CLUTCH INSPECTION
This motorcycle is equipped with an automatic clutch and vari-
able ratio belt drive transmission. The engagement of the clutch
is governed by engine RPMs and centrifugal mechanism located
in the clutch.

assembly it is essential that the clutch engages smoothly and
gradually. The following inspections must be performed:
1. INITIAL ENGAGEMENT INSPECTION

• Remove the front frame cover. (!5-8)
• Connect an electric tachometer to the high-tension cord.
• Seated on the motorcycle with the motorcycle on level
ground, increase the engine RPM slowly and note the RPM at
which the motorcycle begins to move forward.
