So I noticed that my bike is only running on one cylinder. I get some occasional back firing when I rev the throttle a bit. Plenty of spark at the end of the wire to the frame. Tried swapping coils, the primary wiring and the secondary wiring to see if the problem would follow a specific coil. It did not. I removed the carbs, poked around with them a bit, the float bowls are getting gas, the slides appear to be operational. Everything looks clean, no gunk, no goo. Sprayed some starter fluid into the back of the carb in question and I got some idle raise. Im at a loss as to what to check next. Do I just do a complete tear down of the carbs? It would appear that I have 2 parts of the air/fuel/spark combination thats required for combustion..... Any tips? Pointers? Something really simple that I'm missing?
