Why does my motorcycle backfire on deceleration?
Backfires on deceleration is simply the process of burning the excess fuel left the combustion chamber. First, is when the exhaust ports open, the change in pressure causes a very lean mixture of fuel and air. The fuel and air are still burning at this time, but very slowly.

What to do if your Harley backfiring on deceleration?
Don’t “change the plugs” like some people suggest, it’s a waste of time and money. Messing with the ignition timing really won’t help either, because it is still a lean fuel/air mix on deceleration that is the cause.
Why does my car backfire when I let off throttle?
Backfiring happens all the time, in cars and bikes, you just don’t hear it because the muffler/exhaust. Since you’ve modified it, now you do. What it is, is incomplete combustion, fuel is left over, and shot into the exhaust pipes.
What causes a Harley Davidson engine to ” fire “?
The engine is still spinning but the incoming fuel rate is very low, until just enough builds up in the combustion chamber to “fire” on the exhaust stroke of the engine. Don’t “change the plugs” like some people suggest, it’s a waste of time and money.

What causes a car exhaust pipe to backfire?
Backfiring happens all the time, in cars and bikes, you just don’t hear it because the muffler/exhaust. Since you’ve modified it, now you do. What it is, is incomplete combustion, fuel is left over, and shot into the exhaust pipes. The heat from the pipes then ignites the vapor and boom, backfire.
