Hi,
I have been struggling with an issue with my XS500B. The engine has been rebuilt. Re-bore, new seals, gaskets etc. I took it apart because it was smoking from the right cylinder and running very rough. So imagine my frustration when it was still smoking from the same side! So I took it apart again and checked the valve seals, barrels, cylinder head for cracks etc etc etc. I carefully re-assembled it and guess what? The problem is still there.
What am I missing? Is it something other than mechanical? Electrical? Fuel? I have replaced the coils and condenser. I also have rebuilt the carbs with a re-build kit and kept the standard airbox and filter. The airscrews don't seem to do much though?
Please help
