The drive p ulley 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 maximum engine RPM to
maintain maximum power.
Ramp cams should be adjusted so that actual maximum engine
RPM matches the maximum horsepower RPM. Refer to
SPECIFI-
CATIONS (ENGINE)
.
NOTE: Use a precision d igital tachometer for engine RPM adjust-
ment.
There are 5 positions in which the ramp cam can be set.
Each position modifies the maximum engine RPM by about 200
RPM.
Lower position numbers decrease engine RPM in steps of 200 RPM
and higher position numbers increase it in ste ps of 2 00 RPM.
