The engine can be tuned with the optimized control angles of our shaft as if an original Piaggio shaft was used. Nevertheless, the extended intake angle ensures that even completely made engines can turn at full power.
In addition, the rotary vane inlet of the housing can be extended to create enough space for larger carburettors and to further increase the engine's performance.
