EMISSION CONTROL SYSTEMS
Noise Emission Control System
Do not modify the engine, intake or exhaust components, as doing so
may affect compliance with state and local noise level requirements.
Spark Arrestor
Your Polaris ATV has a spark arrestor that was tested and approved in
accordance with the USDA Forestry Service Standard 5100-1C.
Exhaust Emission Control System
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. Blow-by
gases are forced back to the combustion chamber by the intake system.
The system does not allow the blow-by gases to enter the atmosphere.
