RD400 / RD350 / RD250 / R5 Fuel System
The air-fuel ratio that keeps your vintage Yamaha RD café racer running as good as it looks is delicate, and it doesn’t take much to disrupt it. Mikes XS carries RD250, RD350 and RD400 carb repair kits that will help restore your vintage Yamaha carburetors to peak performance. We also sell the float bowl gaskets, float needles, main jets and float valves separately. For a complete fuel system overhaul, replace that aging RD350 petcock with one our brand-new, non-vacuum-type models.
