INITIAL ENGAGEMENT AND CLUTCH LOCK-UP INSPECTION
The LT-Z250 is equipped with a centrifugal type automatic
clutch.
To insure proper performance and longevity of the clutch
assemblies, it is essential that the clutches engage smoothly
and gradually. Before checking the initial engagement and
clutch lock-up, two inspection checks must be performed to thor-
oughly check the operation of the drive train. Perform the follow-
ing:
Check the oil level. (!2-10)
Warm up the engine.
