Carburettor diaphragm Yamaha SR250 / XJ 650 / 900 / 1100 Tourmax

Carburetor membrane from manufacturer Tourmax for Yamaha SR250 / XJ 650 / 900 / 1100.

The carburetor membrane is a key component in the intake system. Its function is to regulate the opening of the carburetor slide according to the vacuum generated by the engine, thus allowing precise dosing of air and gasoline.

Over time, the membrane can deteriorate, develop cracks, or lose elasticity, causing issues such as jerking, lack of acceleration, loss of power, or difficulty maintaining idle. Replacing it is essential to restore the correct functioning of the carburetor and ensure an optimal air-fuel mixture.
