polaris restrictor disk

The Polaris restrictor disk is a small plastic ring that is placed inside the carburetor of certain Polaris snowmobile models to limit the amount of air that flows into the engine. This restricts the amount of power the engine can produce, making it more suitable for novice riders or for use in areas where there are noise and emission restrictions.

The restrictor disk works by limiting the size of the carburetor opening, which reduces the amount of air that can flow into the engine. This in turn reduces the amount of fuel that can be burned, which limits the power output of the engine.

It is worth noting that removing or tampering with the restrictor disk can affect the warranty on the snowmobile and may also violate local laws and regulations. If you are considering modifying your snowmobile in any way, it is important to check the manufacturer's recommendations and consult with a qualified mechanic or dealer.
