Hiya. Just got a 76 xs which has been standing a few years 2700 miles on the clock and original tyres on so presume genuine mileage. The bike will start and run but runs very weakly on the RH cylinder. It chuffs through the carb and when you pull the plug lead off it only slows the revs down a little. Valve clearance is fine and the compression is good. Is there any chance that the valve timing is wrong ? Lh cylinder seems to be running fine. It also sounds a little strange through the RH exhaust. Please help !
