Hello all. I am a long time, avid motorcyclist. I picked up a 1100 late fall, as a rescue bike. The long and short is this, I have been through the carburetors ad nausea. The jets are clean, the passages are clean. I installed new floats, new carb holders, and new diaphrams. I welded up the few holes in the exhaust, so it is all good there. I balanced the carbs, although the bike is not running correctly. 1 and 4 are running fine. 2 and 3 backfire at low engine speed. Crank the throttle, and she screams. All jets match across all carburetors. Unless there is some magical idle jet passage I am not seeing here, the bike should run tip top. I boiled the carburetors last night, and no change! Engine timing is set properly as well. To be honest, I am just flat out of ideas, and need help. If I cannot figure this out, I will have to part her out........
Where to look guys? could this be a bad coil? I know 1 and 4 run together, as 2 and 3 do. Never seen a bad coil cause back fire at low speed, just flat dead miss.... HELP!!
Thanks from snow covered MI!
