DetailsPolini offers a so called Big Valve kit for most of the scooters that are originally only equipped with a 2-petal reed block. The kit consists of a reed valve with 4 petals and the matching intake manifold. Thanks to the considerably increased intake cross-section of the 4-petal reed valve (already a stock part in e.g. horizontal Minarelli and Piaggio engines)and a bigger carburetor, you have the advantage of greater cylinder filling and the engine’s performance is better throughout the whole power band. Intended to be used with 21mm Dellorto PHBG carbs.
Included in the delivery are a BigValve intake manifold and a reed valve.
The only carburettor to fit is the Dellorto 21mm!!
Also available: intake manifold Big Valve from Giraudeau, part nr: A145130.
