Drive Pulley Adjustment

WARNING
Remove tether cord cap before performing any maintenance
or adjustment, unless otherwise specified. Vehicle must be
parked in a safe place, away from the trail.
General
All Models except 4-TEC
The drive pulley is factory calibrated to transmit maximum engine
power at a predefined RPM. Refer to SPECIFICATIONS at the end of
this guide. Factors such as ambient temperature, altitude or surface
condition may vary this critical engine RPM thus affecting snowmo-
bile efficiency.
This adjustable drive pulley allows setting maximum engine RPM in
the vehicle to maintain maximum power.
Calibration screws should be adjusted so that actual maximum en-
gine RPM in vehicle matches with the maximum horsepower RPM.
NOTE: Use precision digital tachometer for engine RPM adjustment.
NOTE: The adjustment has an effect on high RPM only.
Calibration screw has a notch on top of its head.
