Why does my bike backfire when I let off the throttle?
Beside above, why does my motorcycle backfire when I let off the throttle? 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 the fuel. Member.
How do you fix a popping motorcycle exhaust?
There are many ways to stop the bike from backfiring and some of them are as listed below.
- 1) Keep a Check on the Carburetor. The engine will run clean if the fuel cannot flow properly and the main cause for this is a dirty carburetor.
- 2) Fuel Injector Cleaner.
- 3) Keep a Check on your Jets.
- 4) Change Fuel Grade.
Why does my engine pop when I let off throttle?
Idle is 1500rpm. I never have popping or backfire during idle, cruising speeds or under accelleration. Only time I’m getting it is if I open up throttle to speed up rapidly, then let off throttle.

It’s a matter of degrees. Large pops can signify a mixture that’s way off, while some bikes may pop a little at peak efficiency. Removing the baffles will generally require a jet change or remap. Performance is hindered or engine damage can occur if it’s not done properly. The easiest way to gauge is by checking plugs.
What happens when you let off the throttle?
Not uncommon, should happen when decelerating in gear, the explosions aren’t as violent, and don’t get as much gas burned, so left-overs happen.
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 exhaust to pop when letting off throttle?
Plugged slow jets not uncommon (and that can cause other major problems. If the bike never did it, sat a long time and started popping, that’s more of a possibility). Incorrect air screw settings can sometimes cause it, I’ve been able to tune it out (or hide it..) with an air screw adjustment in some cases.
Why does my engine pop when I decelerate?
This fresh air makes the exhaust hotter (think of letting a fire have more oxygen) which aids in the combustion of the unburnt fuel. To REDUCE (it may not totally go away) popping on deceleration first make sure that you do not have any intake or exhaust leaks.
How can I Stop my Car from popping on deceleration?
To REDUCE (it may not totally go away) popping on deceleration first make sure that you do not have any intake or exhaust leaks. If all that checks out then you can alter the fuel curve at closed throttle to help this problem.
