DRIVE PULLEY ADJUSTMENT
The drive pulley is factory calibrated to transmit
maximum engine power at a predefined RPM.
Factors such as ambient temperature, altitude or
surface condition may vary this critical engine
RPM thus affecting snowmobile efficiency.
This adjustable drive pulley allows setting maxi-
mum engine RPM in the vehicle to maintain max-
imum power.
Calibration screws should be adjusted so that ac-
tual maximum engine RPM in vehicle matches
with the maximum horsepower RPM given in
TECHNICAL DATA 10.
NOTE:
Use precision digital tachometer for en-
gine RPM adjustment.
NOTE:
The adjustment has an effect on high
RPM only.
To adjust, modify ramp end position by turning cal-
ibration screws.
