I bought this 1983 XS650 and wasn't running right, the kid messed with jetting so I bought a TC Bros Mikuni setup pre-jetted. I am at sea level. I immediately got a right side exhaust backfire which at times ran back through the carburetor. I depressed the choke and it went away but the tight side plug fouled as it was running so rich. I went a step further and got the billet intake and new rubbers / clamps and it didn't change, still have backfire. I have an exhaust leak on the left side which I will fix.
I cant figure out why the pap-pap-pap pow ! sound even though I have new carbs and intake. I don't have points or timing on the 1983 model. Help ! I don't have enough experience with these bikes as I do with my Harleys.
