I just rebuilt all 4 carbs due to sticking float. Besides that the bike ran great before. I replaced everything besides jets and diaphragm/slide. Re installed. Bike starts, idles, and runs great until I get on it the front right cylinder is popping and misfire/backfiring. Does it more when it´s hot. At an idle it sounds great. If I Rev it up and let go of the throttle, that one cylinder pops and sounds like a gun shot????
