If you're rolling off the throttle and getting some deceleration popping, that might be completely normal. My 08 doesn't do it but that is probably the mapping I put in when I installed my full system exhaust. It was a map created by the supplier I bought the pipe from.

If you have an aftermarket exhaust, you might be able to reduce or eliminate the popping with a good AFR tune. Personally, I love deceleration pops. If it's just running a little rich at 0% throttle, I'd leave it alone and enjoy the sound.

Deceleration popping is different i njoy that ….bt this i am just crusing and under 4000 rpm the popping sounds comes while deceleration

If the popping is coming from your muffler when you decelerate, that would be deceleration popping. My busa never did that but my ZX-14 did it very much a little at 4000 rpm and a lot at 2500.

Is the pop you are describing coming from somewhere other than the exhaust?

Can you record the audio and load it to YouTube?

If you recently changed plugs make sure you reinstalled the airbox correctly and didn't mix up the hoses. Almost sounds like a PAIR valve issue.

This is the correct way it goes in. Screen facing up. I don't know if it will fit with the screen facing down.

I have my entire PAIR removed and blockoff plates ubstalled. Mine still never pops except for rare occasions on a hot day when I'm riding hard it might pop once.
