Yamaha XS650 BS34 38 CV Mikuni Carb Slides, Carb Top Parts and Throttle Butterfly Parts

When the diaphragm on a Yamaha XS650 carburetor slid deteriorates, performance issues quickly follow. Unfortunately, replacement is the only solution. Mikes XS carries XS650 carb slide and diaphragm assemblies for Mikuni BS34 and BS38 carbs to cure this uncommon problem. We also offer hard-to-find XS650 carb replacement parts like the Mikuni BS34 butterfly shaft seal, carb lid screws, slide needle preload springs, float needles and Dyno Kit performance jet needles.
