Pilot screw badly stuck in my LH carb ended up with the threads destroyed and pilot still in there. Need a replacement LH carb body, or would consider full carb or set of carbs. BS34 style, my bike is a 1980 but I believe its the same carbs '80-'84. Let me know what you've got. Thanks!

Looking for throttle shafts for XS650 BS34 carbs. I need the plate and shaft for the right carb for sure but will likely need both. My carbs are 1980 and I am assuming that all bs34's for xs650s were the same except for the floats.

Working on my 1980 XS and found I had leaking carb shaft seals. Ground down the staked ends of the throttle plate screws but could not get the screws out. I tried drilling out the screws on the right carb and fear I didn't get the drill centered in the screw and will never get the threads clean...

I have been thinking about updating my carbs for a few reasons. Let me know if these are a good direction to stock carbs. As stated in the title I just bought a 1975 xs 650 that is bored out to a 750. I am having some issues with the engine and I am thinking carbs may be part of the problem...

Not good with carb stuff. Can anyone suggest a good shop to rebuild my 38mm Solex carbs or a 72 XS2?

Just got done with an engine rebuild on my 81 xs650 special. Started it up after getting the motor back in and its running on pretty much one cylinder. It's getting spark, I checked it on the side of the motor. It's theoretically getting fuel, we sprayed ether into the carb on the weak side...
