Yamaha XS650 BS34 38 CV Mikuni Carb Floats, Float Valves and Choke Parts

Flooding carbs cause hard starting and poor performance for your Yamaha XS650, but don’t throw money away on a new set of carburetors when a simple float replacement could cure the problem. Mikes XS is your source for Mikuni BS34 and BS38 CV floats, float hinge pins and float bowl gaskets. We also carry XS650 choke plungers, float needles and seats, float bowl mounting screws and float bowl gaskets to help you complete your Yamaha XS carburetor restoration.
