To take advantage of the positive effects of a large carburettor (more power, more torque, more draft), Polini uses a clever trick. The passage of the carburettor opens after the slider to a much bigger diameter, simulating a much bigger cross section.
So the Polini CP carburettor with 23 millimetres of passage gives much more power than a PWK24 carburettor.
Thanks to the small dimensions and the integrated intake manifold, the CP carburettor is ideal on all high performance engines where a small size is an advantage.
- Height: 118.5 millimetres
- Width: 66 millimetres
- Depth: 70 millimetres
- Connection width air filter side: Ø46 millimetres
- Connection width engine side: Ø28.5 millimetres
The carburettor has a round slide valve and connections for vacuum/oil (rubber caps are included). The main jet is identical to those of the Keihin PWK, all other tuning parts are Polini's own. The carburettor has a cable operated cable choke (choke not included).
- main jet: 110
- secondary jet: 40
- slide needle: 14/22
- slide: 24x30°
- needle nozzle: Ø2.7mm
