Polini Motorcycle carburettor Cp

An innovative carburettor, with each component designed, developed and manufactured by the company from Bergamo. Available in a wide range of diameters - 15/17.5/19/21/23/24 - it is made entirely of aluminium, has compact dimensions and is 40% lighter than a traditional carburettor. The intake manifold is very short and features an exclusive axial design with a geometry that optimises airflow as the gases pass through. The fuel overflow in the spray nozzle has been designed to ensure correct flow dynamics in every position of the throttle valve when it opens. The fuel entry port and the wider needle allow for consistent draw even in the most extreme conditions. The float level, made entirely of plastic, and the needle seal are carefully monitored during production to ensure the same efficiency over time.
These features greatly simplify the adjustment of the carburettor. Thanks to extremely sophisticated calibration, the fuel-air flows, main jets, and low jets have been designed to achieve the best performance while reducing consumption. The compact dimensions of the new carburettor are the result of careful and meticulous management of the internal space and the maximum efficiency of all components, which are subject to strict controls.
To ensure easy and precise installation on the best-selling engines and compatibility with various filter housings, both original and replacement, the carburettor has been designed to be mountable on the most popular engines, and to be compatible with different filter housings.
