intake system Naraku Big Valve V.2 for Minarelli horizontal

Naraku Racing Intake V.2 including 2 adapters for all common carburettors. The 23mm adapter is suitable for all Dellorto 10-21mm and Arreche 17-21mm carburettors. The 32mm adapter allows for instance the mounting of PWK carburettors with an opening of up to 30mm. Includes NBR Racing reed block and fixings. The somewhat longer design accelerates the gas flow, which helps the engine produce more power. Unfortunately for Aprilia SR 50, the length means that the fit must be reworked a little, as the intake interferes with the frame. Recommended for cylinders from 70cc and sizes of carburettor from 19mm.
