Since I did my stage one two weeks ago with the screamin eagle high flow filter there is more of a high pitched whirring noise coming from the right side. I had the bike dyno tuned a couple of days after and the tech said it is running awesome, said it was "one happy bike." I'm hoping that this sound is just the effect of the higher air intake level. Is this right?

 

All high flow cotton filters have air sucking noise, not to worry.
