Yamaha XS650 Fuel System Parts
Clogged XS650 carb jets and needles cause poor performance and annoying backfiring while down shifting and engine braking. Mikes XS stocks brand new XS650 main jets, floats and float needles, carburetor spacers, O-rings and more for Dellorto, PWK, Mikuni and Keihin carburetors.
Old worn out carb boots can cause similar performance issues, but they are often overlooked. If your issues persist, check your XS650 carb holders for checking and cracking. If there is an issue, replace them with a new set of XS650 carb boots from Mikes XS. We can also provide XS650 fuel filters, fuel hoses, performance pod air filters, and billet aluminum intake manifolds.
Mikes XS is also a great source for XS650 petcocks, fuel valves, fuel caps and gas cap rubber seals, and we stock petcock rebuild kits as well. And if your acceleration is starting to glitch out, try renewing the throttle cable. We have Mikuni and PWK-type XS650 throttle cables and extended throttle cables, as well as throttle sleeves, universal grips and vintage-grip throttle assemblies. If it makes an XS650 go, Mikes XS probably has one.
