Why does my ATV pop when I let off the gas?
Why do ATV’s Backfire? ATVs usually backfire because of a short, sudden moment where the engine is running too rich or too lean. That means that it’s either getting more fuel than it needs for the amount of air it takes in, or else not enough.
Why does my bike backfire when I decelerate?
Backfiring 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.
Why does my car backfire when I let off the throttle?
When I let off the throttle and the engine is slowing the car down (4 speed manual), I’m getting an exhaust backfire. It’s much more intense when coming off of hard acceleration. Now, I understand this can be either a lean or rich condition at throttle lift where un-burned fuel collects and ignites in the exhaust system.
Why does my ATV keep backfiring at idle?
Take note that most ATVs source fresh air at the junction of mufflers and header pipes. If there’s a leak along the system, the engine will keep backfiring. In some instances, a popping exhaust system indicates that the engine has an extremely lean idle circuit.
How often does the exhaust backfire on deceleration?
The backfire is 2 consistent pops, one right after the other. I’m going to drive the car today and watch the AFR reading to determine whether it is going lean or rich when the exhaust pops. My question is, when you lift off the throttle does the Atomic cut off fuel?
What happens if you backfire on a motorcycle?
On the other hand, a strong backfire can result in serious damages like cracks in the exhaust manifold. Worse, you may have to undertake costly and extensive repairs to get the engine working pop-free again. All in all, a backfire will hardly cause injuries to the rider.

It’s much more intense when coming off of hard acceleration. Now, I understand this can be either a lean or rich condition at throttle lift where un-burned fuel collects and ignites in the exhaust system. I’ve already checked and ruled out vacuum and/or exhaust leaks which would introduce fresh air into the system.
