reed valve assy racing for Minarelli horizontal

The largest intake manifold is of no use if a flow-restricted diaphragm block is waiting afterwards. With this inexpensive racing diaphragm block, you can now clear the way for your mixture. The expanded passage allows greater gas flow volumes in the same time.

The rubber-vulcanized fiberglass diaphragms not only seal better than conventional diaphragms. Due to their greater flexibility, they lead to more direct response. Even in the event of damage to the diaphragm, they do not lead to total engine damage. The original sheet metal diaphragms of the original diaphragm block, however, do.

Fits all horizontal Minarelli engines, Suzuki engines and CPI, Generic and Keeway models.
