So I picked this bike up off a kid and started by putting new handlebars on it, ordered a seat. It is a classic bobber just like the one I had back in 1984. It ran but had a backfire on the right-hand side only and out the exhaust, not the carb. Everything on it has been thoroughly molested but seems to all work. When I sprayed starting ether in the right-hand carburetor, the backfire went away.
Could it be the right side coil, is there a separate condensor for each side? The plug wire? I am baffled. It starts after about four kicks and with starting ether but runs great once started except for the loud popping noise the backfire makes.
I have read through several threads addressing this but non quite hit it on the head. I know the points are not adjustable on the year bike I have, could the valve need to be adjusted? Could it be a bent valve
?
