CVT System
On this ATV, the approximate gear ratio difference between high and low range is
1:2.05. This difference in gearing affects the operation of the CVT, especially at
speeds less than 7 MPH, due to the system’s dependence on engine speed.
By switching to low range while operating at low ground speeds, the air temperature
in the clutch will be reduced. Reducing the temperature inside the clutch cover
extends the life of the CVT components (belt, cover, etc.)
Adjust the center distance of the CVT:
1. Check and adjust the measurement L1 and L2.
NOTE:
1. Never operate the engine when adjusting the CVT;
2. The adjustment of the CVT must be done by your dealer.
