Does it smell rich like gas isn't being burnt and coming out the tail pipe? If so then it's probably the spark plugs. Actually I bet you any money it is. They're cheap and easy to replace, give it a try.

My 1400 intruder pops and back fires


I think maddogcycle is right. One cylinder is running rich and the other running lean. It seems as though they have not been balanced properly and the mixture not accurately adjusted. The settings on these carburettors are critical and must be adjusted with the proper gauges. I'd advise you to have the carbs cleaned and adjusted and tuned to the engine for balance of inducted air flow and fuel/air ratio (mixture)

Did you sync the two carbs? If not the rear may be getting all the gas from the rear carb and none to the front. Twist throttle engine off and see if front carb cable is pulling the carb open.
Also unscrew the spark plug boot from the front spark plug wire and trim 1/8th inch off the wire and screw the boot back in. The plug wire end may be corroded on that wire.

Check all your wires around your coils to see if they are tight or to see if any are broke. Check your sparkplug caps and coils with a ohms meter.
