In general, backfiring on deceleration (as opposed to acceleration) is generally caused by a lean condition in the pilot circuit. … Then, when the engine does fire, these unburned gasses are ignited in the exhaust pipe, causing the backfire. Then, the classic diagnosis is too lean a fuel mixture.
Why does my car backfire when decelerating?
Backfiring on deceleration is due to unburned fuel being ignited in the exhaust. It is not only much quieter but also does not allow the fresh air to enter the exhaust due to reversion. This fresh air makes the exhaust think of letting a fire have more oxygen which aids in the combustion of the unburned fuel.

Is deceleration backfire bad?
A motorcycle backfire is inherently bad since unburnt fuel is detonating in a mistimed manner and mostly outside the engine. The loss of fuel results in loss of power and low mileage for the motorcycle. In addition, the fuel detonation causes overheating of the engine and the exhaust.
