Exhaust backfire during acceleration typically occurs due to an imbalance in the air-fuel mixture, often caused by a lean mixture (too much air) or unburned fuel igniting in the exhaust system. Other factors can include ignition timing issues, a malfunctioning fuel injector, or exhaust leaks. This phenomenon can also happen if the engine is running too rich, leading to unburned fuel entering the exhaust. Proper tuning and maintenance can help prevent backfiring.

Why a Harley backfires under acceleration?
A Harley may backfire under acceleration due to an overly rich fuel mixture, which allows unburned fuel to enter the exhaust system and ignite. This can also occur if there are issues with the ignition timing or if the spark plugs are worn or fouled. Additionally, exhaust leaks can contribute to backfiring by disrupting the proper flow of exhaust gases. Regular maintenance and tuning can help prevent this issue.

What causes a 1973 Pontiac 350 engine to backfire through the exhaust?
A large backfire is most likely caused by a bad spark plug or plug wire. Unburned air and fuel pumped into the exhaust will often be ignited by the other cylinders still burning exhaust gases. Also check your ignition timing, if it is late and you have a rich mixture you can get a backfire. An exhaust leak will let air enter the exhaust under deceleration and cause a "popping" sound.
