Drive Pulley Adjustment
WARNING
Remove tether cord cap (DESS
key) before performing any main-
tenance
or adjustment,
unless
otherwise specified. 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 main-
tain maximum power.
Calibration screws should be adjusted
so that actual maximum engine RPM
matches the maximum horsepower
RPM.
