XS750 / XS850 / XS1100 Fuel System

When a vintage Yamaha petcock decides to start leaking fuel, it is never at a good time. Its gaskets tend to show their age when your engine is at running temperature, meaning you are on the road. Inspect your XS750 restoration’s petcock for signs of age. Mikes XS has XS750 fuel petcock repair kits to restore the proper flow through this sensitive vacuum operated system.

We are also a prime source for vintage Yamaha carburetor replacement parts. We stock XS750, XS850 and XS1100 brass carb floats, float needles and float-bowl gaskets to address another common fuel-leak location on vintage motorcycles. We also stock XS750 carb slides and carburetor rebuild kits to bring your classic Yamaha restoration to life.
