The exhaust emission control system is composed of efficient
carburetor settings with an optimum ignition system. Idle speed can be
adjusted with the throttle stop screw. The carburetor must be
maintained at Polaris specifications to achieve optimal performance.
Crankcase Emission Control System
This engine is equipped with a closed crankcase system. It allows
blow-by gases back to the combustion chamber using the intake
system. It does not allow the blow-by gases to enter the atmosphere.

the vehicle. Hot components can cause serious burns and fire.
Do not touch hot exhaust system components. Use caution when
traveling through tall grass, especially dry grass.
