Another "what noise is this?" thread
2010 Ultra classic. New to me 400 miles ago.
I rode with my half helmet for the first time (Usually use a modular) and I hear this extremely strange tinny sheet metal vibrating noise under hard acceleration. I would swear it is the exhaust heat shields but they are tight. The noise is coming from the front of the engine area. It is not valve train tapping. Nothing else like highway bars, floor boards, etc are loose. Its almost like a mixture of air and sheet metal vibrating. Could it be coming from my air cleaner? Its a Vance & Hines Vo2 intake. I just had the lifters replaced as well as adjustable pushrods. I never heard this noise until I wore my half helmet. I know that fairings (lower and upper) magnify alot of sound. My guesses are noise from the air cleaner or pinging or detonation, although I dont think pinging or detonation would sound like that. I have owned enough Harleys to know that I should expect lots of engine noise, still I would like to hear some opinions. Thanks

Yes I may do that. Also, I think I will remove the lower fairings to see if they are just amplifying the noise.
