Pat, I am getting more popping on one side as well with the 42's. Mine is on the right if sitting on the bike. I believe I don't have enough back pressure from a previous setup mod to my pipes. I would always expect more popping from these carbs as they shut off the fuel at closed throttle pretty quick in comparison to our stockers. You agree?
Or, I could be crazy. Or crazier depending upon whom you ask.
