engine, the vehicle could creep, indi-
cating that the belt is too tight.
If the vehicle creeps, lower the drive
belt height from the preliminary set-
ting. Repeat procedure until creeping
stops.
Reverse Activation

WARNING
Remove the tether cord cap and
key before performing any adjust-
ment. Vehicle must be parked in a
safe place, away from the trail.
The drive pulley is factory calibrated to
transmit maximum engine power at a
predefined RPM. Factors such as am-
bient temperature, altitude or surface
condition may vary this critical engine
RPM thus affecting snowmobile effi-
ciency.
This adjustable drive pulley allows set-
ting maximum engine RPM to maintain
maximum power.
Calibration screws should be adjusted
so that actual maximum engine RPM
matches the maximum horsepower
RPM.
