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. 68
