Reversion question
I currently have a 2012 Street Glide 103 with 57H cams and open a/c. I have the reversion knock knock at certain rpm's and throttle position.
The exhaust I'm running is a cobra powerport, 4" rush big louie's with 2" baffles
1) Would changing to a different sized baffle or head pipe quiet the reversion knock?
2) I've also read that changing to 1.75" baffle in left side muffler will help performance. Has anyone tried this with good results?

I have the same issue with my cam as does my riding buddy with a 57H. It is an echo off of the throttle body butterfly, more of a cluck than a knock and it is caused by the cam overlap. It's the price you pay for the great performance of that cam design. A football AC cover will help, but different pipes won't do a thing.

Thanks for the reply rockajet1. I called fuel moto and they told me the same thing. I pulled the oem football cover off my wife's bike and went for a ride, what a difference as the noisy clucking was muffled down to something I can live with. Unfortunately for me as I like my naked air cleaner I will be returning to the football style cover.
