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 vehicle has a spark arrestor that was tested and approved in accordance with the USDA Forest Service Standard 5100-1C. Federal law requires that this spark arrestor be installed and functional when the vehicle is operated on public lands. 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. 89
