Stage6 Intake System - CPI / Minarelli Horizontal A complete intake system from Stage6. The big 2-petal reed block combined with a carburetor of 19mm or larger ensures enormous cylinder filling which is essential for good performance. The carburetor adapter can be replaced in order to mount larger carburetors such as Stage6 PWK / Keihin PWK, Stage6 TM24 / Mikuni TM24 or KOSO 28mm. The included adapter fits Dellorto 10-21mm and Arreche 17-21mm. Attention: Due to the longer shape, the original airbox will have to be replaced with a racing air filter. Furthermore some models (e.g. Aprilia SR) require the intake manifold or the frame to be modified so that the carburetor will have enough space. Gaskets not included. Note: Please make sure this scooter engine part fits your particular scooter model. Many scooters have the same name but use different engine parts depending on the year of manufacture.
