Hi, Mmme3331 if your carburetor or exhaust is:
COUGHING is usually caused by an air leak in the intake system and will generally have the same telltale signs, a wet or damp build up of oil/gas seepage at the intake manifold to cylinder head or carburetor to intake manifold connection and in rare instances a worn throttle plate shaft and or seals.
POPPING on deceleration is usually caused by a lean fuel condition or an air leak in the exhaust system and is generally located where black carbon soot is seen as a flashing build up from any joint connection. This condition can easily be remedied by removing and cleaning both joint pieces and reassembling with high temp silicone and torquing the exhaust clamp to the proper spec.
SPITTING is usually caused by a faulty accelerator pump and or nozzle, or the float bowl needle and seat leaking and overflowing through the main jet mixing well nozzle, or the air-fuel mixture screw is adjusted too lean.
BACKFIRING is usually caused by a sticky/tight intake valve or a timing issue, 180 degrees out or cam chain off 1or 2 teeth.

Probably the idle jets are set too lean. From what I have read, the factory settings are often wrong. Drill out the plugs and adjust. If you use the right size drill you can get in with a small screwdriver and make the adjustments without totally removing the plug. This eliminates the possibility of losing the adjustment screw, which can happen if the plugs are not there.

Best thing to do is put in a Cobra stage 1 jet kit. You will be amazed at how much better the bike runs.

Hi, Wes 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).

Is popping or backfire normal?


Two things can cause popping or backfiring on deceleration. The most common is air leaking into the exhaust through the exhaust pipe copper o-ring gaskets. This typically happens when the exhaust is replaced without removing the old ones (doubled up) or simply reusing the old gaskets and they don't seal. The other thing that can cause popping is bad air cut diaphragms on the carburetors. If they are old and sticky or have holes in them they don't properly shut off the gas on deceleration causing the backfire.

My 2002 ace shadow 750 has a back firering problem. The dealer that I take it to says thats just the way it is any thoughts.


If the backfiring is only on deceleration, the problem is most likely carburetors that are out of sync.
