I’m fixing up a barn find that’s been sitting for a long time, since 83 I believe. Spent the last 2 months cleaning and redoing the gas tank (3 step process), new battery, ''new'' plugs, condenser, points, coils in working shape, new fuel lines, soaked and cleaned carbs spotless. All the electrical works.
It starts and will idle great, but only the right cylinder seems to be getting full power. The points are within spec, and both cylinders are getting fuel and spark. It sometimes will backfire through the left carb, and the left exhaust will make an almost whistle sound, like its choking. There is some pressure exiting the left exhaust, but nothing like the right exhaust. Both exhaust manifolds are hot. I tried switching mufflers, still no effect. Last time after running it for a while, when I turn it off, smoke exits from the left carb. Not a crazy amount, but still some smoke.
I’m thinking maybe the timing is off and/or the valves are out of spec? Anything else I should check? I can only work on the bike two days a week because of work, so trying to plan in advance anything I should do.
Thanks for your help on this matter , I have found myself totally stomped this time around! ???
