This engine is equipped with a closed crankcase system. Blow-by gases are forced back to
the combustion chamber by the intake system. All exhaust gases exit through the exhaust
system.
Exhaust Emission Control System
The emissions from the exhaust of this vehicle are controlled by engine design, including
factory-set fuel delivery and ignition. The engine and related components must be
maintained at Polaris specifications to achieve optimal performance.
Engine idle speed is the only adjustment Polaris recommends that the operator perform.
Any other adjustments should be performed by an authorized Polaris dealer.
The emissions label is located on the recoil cover or stator housing.
