Polini CP 21 carburetor incl. air filter for your Piaggio Ciao, Si, Bravo and Boxer moped / moped.
The new racing carburetor was launched together with the new EVOLUTION parts and matched to the new Polini EVO REED engine components.
The racing carburetor has a compact design and is around 40% lighter than comparable carburetors. The air flow is optimized thanks to the short intake path and the circular passage. The larger needle and an adapted mixing tube support the atomization of the gas mixture. This makes it very easy to tune the carburetor. In addition, consumption is reduced even at high power levels.
In addition to the 84cc main jet, an 82cc and 86cc jet are also included in the scope of delivery. It is attached to the intake manifold by means of a rubber sleeve.
Note: It seems that Polini did not take sufficient account of the fact that the idle throttle screw is on the wrong side when developing a carburetor for the side intake on the Piaggio.
Matching nozzles and other parts from the EVO series can be found in the accessories section.
Quality product from the Italian manufacturer Polini.
