membrane

A diaphragm is a flexible membrane located in the carburetor or intake port of your moped or scooter. It regulates the flow of fuel and air and plays a crucial role in smooth and efficient combustion. With a worn or torn diaphragm, the engine may start poorly, run irregularly, or deliver less power.

Choose a diaphragm based on your vehicle's engine block and brand — the size and shape vary by engine type. On this page, you will find diaphragms for a wide range of popular mopeds and scooters, including models with Minarelli, Peugeot, and Piaggio engines.
