I'm not sure if your hearing the same thing I am. Does it sound like pressure being being relieved or stabilizing. I've never heard this in my Ultra until after the 1000 mile insp was complete.
I'm not HD savy but we could be hearing same animal.
I have the same thing. I always thought it was my wife whistling at the sight of her "bad boy" husband pulling into the garage... she informed me that it was not :15:
If you have a high flow AC such as screamin eagle ect. then I'd say it is indeed air whistling through the air cleaner. Mine does it all the time now after installing the AC never noticed it before I did this
That must be it, I do have an SE air cleaner. You guys are the best. I love Coming to the forum for help and on rare occasions helping someone else newer that me.
