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 Exhaust emissions are controlled by engine design. An electronic fuel injection (EFI) system controls fuel delivery. The engine and EFI components are set at the factory for optimal performance and are not adjustable. 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. 64
