AUTOMATIC CLUTCH INSPECTION

This motorcycle is equipped with an automatic clutch. The
engagement of the clutch is governed by engine RPMs and cen-
trifugal mechanism located in the clutch.
To insure proper performance and longer lifetime of the clutch
assembly it is essential that the clutch engages smoothly and
gradually. The following inspections must be performed:

1. INITIAL ENGAGEMENT INSPECTION

• Warm up the engine to normal operating temperature.
• Connect a 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.

RPMs sustained during the test cycle.
Do not apply full power for more than 3 seconds or
damage to the clutch or engine may occur.
