Carburettor kit 21mm CP manifold and Polini vertical Minarelli air filter

Kit Carburettor CP 21mm manifold and Polini air filter for Minarelli Vertical.

When you start tuning the bike, there comes a point when the original intake starts to fall short.

The kit is made up of several products, including the well-known Carburettor Polini CP Ø21 mm. With a larger diameter and by fitting the shorter intake manifold, they allow the engine to be fed with a greater flow. This translates into quicker throttle response, better engine filling, and a different power curve.

It is not simply a matter of fitting a larger Carburettor. Polini brings together in one kit the 21 mm CP, the 360° rubber manifold, and a higher-flow air filter, so that the entire Air intake works together to achieve superior performance.

The 360° manifold allows the Carburettor to be positioned to find a suitable mounting position, while the higher-flow filter removes part of the restriction that the original system may create.

Carburettor setup:

• Main jet: 100.
• Pilot jet: 40.
• Needle: 14/22.
• Valve: 24x30.
• Spray tube bushing: Ø2.7 mm.

The kit includes:

• Carburettor Polini CP Ø21 mm.
• 360° rubber manifold.
• Higher-flow air filter.
• Starter.
• Throttle cable and starter.

Important: after installation it is necessary to correctly adjust the carburetion according to the Cylinder, exhaust, and the rest of the installed components. The supplied setting is a starting point and may require modifications.
