POLINI BIG VALVE valve box, the most efficient admission of the vertical minarelli, a big, wide, short admission, all with the right injection angle! It is an aluminum box that have it added in order to be able to pass valves size: MINARELLI AM6 from 50cc to gearbox. The pipe is excellent, very well studied in order to be short, to absorb the shocks very well all in too much movement in the big bumps, however they are very badly finished both in terms of pressing, gasket, carburettor mounting so has to be touched up slightly. Our taste, The valves are of size am6 therefore easily replaceable, however not venturized, equipped with stop slats and not necessarily very efficient, we have personally mounted this pack on a prototype and equipped it with v force TPR valves from am6, the result was impressive, we gained in torque, peak, acceleration resumed…, the assembly is otherwise quite simple, the aluminum box is micro blasted in the rules of the art and very well finished. It is also delivered with 3 sets of carbon valve slats to fine-tune the settings! You will understand, it is the ultimate parts on any large configuration of vertical minarelli.
