Polini CP 21mm Carburetor Manual Choke Clamp Mount 201.2102

The genuine Polini CP 21mm carburetor with manual choke (part number 201.2102) has been fully designed and manufactured by Polini for sporty and tuned 2-stroke scooters, mopeds and motorcycles. Thanks to its compact aluminium body, lightweight construction and excellent tuning characteristics, the Polini CP series has become one of the most popular carburetors for road and racing applications.

With its 21 mm venturi, this carburetor offers an excellent balance between low-end torque, throttle response and top-end performance. In our workshop, we almost exclusively fit Polini CP carburetors on engines up to approximately 70cc because they are easy to tune and consistently deliver excellent performance.

This version features a round slide, a manual choke, a fuel inlet and two additional ports that are factory capped. This allows the carburetor to be used with or without a vacuum connection and oil feed connection, depending on the engine setup.

The carburetor has a 24 mm clamp-on connection and can be used in combination with a suitable clamp-on intake manifold. It also features a 46 mm air filter connection.

Compatible air filters:

• Straight: Polini CP 46 mm straight air filter
• 30° bend: Polini CP 46 mm air filter with 30° bend
• 90° bend: Polini CP 46 mm air filter with 90° bend
