Polini CP 19 carburetor for your racing moped, moped and small motorcycle with the highest demands. The racing carburetor developed by Polini 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.
Fastening to the intake manifold is by means of a rubber sleeve.

Installed secondary jet: 40
Ø Nominal: 19 mm
