What is decel popping?
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel.
What is decel pop on a motorcycle?
Deceleration pop is from raw fuel detonating inside your pipes. If you spent the cash on a proper fuel programmer, one like the V&H Fuelpak or Power Commander then your fuel map may be a bit too rich and needs to be leaned up a bit in a few places.
Why does my car pop when I decelerate?

Why do cars pop on deceleration?
Does backfire damage engine?
Backfires and afterfires are worth paying attention to since they can cause engine damage, power loss, and decreased fuel efficiency. There’s a variety of factors that can cause your car to backfire, but the most common ones are having a poor air to fuel ratio, a misfiring spark plug, or good old-fashioned bad timing.
Is decel pop rich or lean?
Popping on deceleration can be caused by both lean or rich Air-to-Fuel mixtures. The most common reason for exhaust popping on deceleration is a lean condition.

What does decel mean on a plane?
The DECEL system was introduced in modern commercial aircraft design to enhance energy management in relation to descent and approach planning while also assisting in easing the flight crew workload. On the Flight Mode Annunciator (FMA) of the aircraft, “DECEL” will be displayed at the calculated DECEL waypoint.
What is the decel indication?
The DECEL indication is based on correct descent planning being planned and executed. The DECEL system was introduced in modern commercial aircraft design to enhance energy management in relation to descent and approach planning while also assisting in easing the flight crew workload.
What is after-Burn and back-fire?
After-burn is similar to back-fire, which is the burning of fuel in the intake port of the carburetor. Both conditions occur when a very lean air/fuel mixture burns so slowly in the combustion chamber that it is still burning when the exhaust and/or intake valves open. Now back to the list… 2.
