can anyone that's experienced it watch my video, every now and then I'll get this sound you hear like there's a dead cylinder. If I give it more gas it'll go away but most the time when at temp it's not there. Occasionally I hear it like this and just the other day for the first time at idle it started making a loud knock so I revved it up and it cleared up

You mean the snapping? Not entirely sure what it is, but I'm guessing you are straight-piped? I've heard it on /both/ of my straight-piped IDIs right somewhere in the 2K-range both accelerating and decelerating. Below that - quiet. Above that, different sound.

I think it has to do with lack of backpressure on the exhaust maby?

I would agree with the above, just sounds like horrible noise a straight piped idi makes. Is there another noise that isnt picked up on the video?
