Two-stroke inlet control via membrane

membranes are used exclusively in the two-stroke engine. With this membrane tongues , the suction path is sealed to the outside so that the previously aspirated mixture can be precompressed and flushed into the combustion chamber. Leaky and broken membranes are a common cause of poor or no longer starting engines, especially for 50cc scooters. Diaphragms are wearing parts and must be changed at regular intervals. Some (often Italian) manufacturers install as standard membrane leaves made of steel. While they last longer than their counterparts made of carbon or plastic but break and are sucked into the combustion chamber, often a major engine damage is the result. For safety reasons we therefore recommend the use of carbon membranes, especially for scooter racing or tuned scooter engines.For almost all scooter models of the major manufacturers such as Yamaha Aprilia Peugeot Vespa Piaggio Malaguti but also for China scooters like Explorer Baotian Rex Sym Keeway Kymco ,  Pegasus , PGO we have both replacement membranes in Standard version or tuning membranes made of carbon.
