CLUTCH
2E331
The clutch may require tuning depending upon
the area of operation and desired handling
characteristics. The clutch can be tuned by
changing engagement and shifting speed.
Clutch engagement speed is defined as the en-
gine speed where the machine first begins to
move from a complete stop.
Shifting speed is when the machine has been
started at full-throttle from a dead stop and has
travelled 200 X 300 m (650 X 1,000 ft).
Normally, when a machine reaches shifting
speed, the vehicle speed increases but the en-
gine speed remains nearly constant. Under un-
favorable conditions (wet snow, icy snow, hills,
or rough terrain ), however, engine speed may
decrease after the shifting speed has been
reached.
