Polini CP Carburetor Features
The Polini CP carburetors are technically advanced carburetors from the Italian scooter tuning experts at Polini.
Polini designed these carburetors to find the perfect balance between weight and performance. The result is a powerful yet very compact carburetor that fits easily and can be maintained or tuned without great effort due to easy access. It is made entirely of aluminum and is 40% lighter than comparable carburetors from other brands.
The intake layout has been modified and is now round instead of oval. The intake path is very short, which leads to accelerated airflow.
Overall, the entire carburetor has been optimized for increased durability, reduced fuel consumption, simplified tuning, and improved overall performance.
Installation is very easy as Polini follows Dell'Orto specifications, so no modifications to the scooter are necessary.
Note: you will need PWK main jets and special Polini CP pilot jets.

Carburetor for scooters, motorcycles and mopeds
The smooth operation and optimum power output of your scooter, motorcycle or moped depends, among other things, on the carburetor, whose job is to create the right mixture of air and gasoline.
How the carburetor works
When the rider operates the throttle, the carburetor slide moves upwards, increasing the air flow that is sucked in through the air filter. The carburetor then mixes this air with petrol, creating a combustible mixture. This mixture is fed into the cylinder through the intake manifold and the reed valve.
The carburetor is equipped with jets to adjust the ratio of fuel and air and thus ensure an optimum air-fuel ratio. It is important that you adjust the carburetor settings to the setup of your engine.
Adjusting the Carburetor
Proper carburetor adjustment is critical for optimal engine operation and durability. Depending on the type of air filter, cylinder and exhaust of your setup, you will need to readjust main and pilot jets. To check the correct operation of the carburetor, you can refer to the color of the spark plug:
- White spark plug = too lean
- Black spark plug = too rich
- Brown spark plug = optimal setting
