This could be any number of things. First consider the most obvious. Change the rear spark plug. Then check the compression in the rear cylinder. If compression is low, it could be a valve sticking or a piston ring wore or a hole in cylinder. If compress is alright, rebuild carbs. I would check out options in a row. I don't think it could be a be the stator or regulator. But it could be. Those would need to be checked out by dealer. Hope tis helps.

hi your carbs need rebuilt if you bought the bike with the cobra pipes on it an aftermarket jet kit has already been installed after time the aftermarket needles wear out and or wear out the emulsion tubes. i had the exact problem tried every thing coils, igniter box etc. check out GMAN INDUSTRIES. COM they will solve your problem. or sell you genuine mikuni parts with the correct jets, pilot screws, and needles.

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.

If they cant duplicate it your good.Usualy with backfiring i would make sure to eliminate any exhaust leaks. The dealer is inexperienced at solving compound problems,(sorry) not picking a fight, but sometimes cleaning is not goog enough,I went through this with a 1400 Intruder.several attempts were needed to get the two carbs level on the same line with each other.so the floats would work properly together,then set fuel flow and the air flow through the ventouri in the carbs.Also i had to make these adjustments while level (not on side stand) The floats were very sencitve to needle valve to seat adjustment(bent to open or close some of the flow)

Hi, Ricky # 8 looks good (air leak) and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.
9. Improper valve clearance (too tight).
