reed valve assy unrestricted for Piaggio

Open diaphragm block. Unlike many original metal diaphragms, this diaphragm block uses plastic diaphragms. Metal diaphragm plates could cause severe engine damage if broken. Plastic diaphragms are simply ground up and disposed of through the exhaust port.

Fits all scooters with 50-180cc Piaggio 2-stroke engines._{AI-translation}
