I recently put Supertrapp SE slipons on the Electraglide. I also put on the SE air cleaner and had them do a remap of the ECM. Sounds good and runs good. When I shut the bike off I get what I would describe as a squeak (for lack of a better words and no it's not a fart) out of the air cleaner. Sounds like a quick blast of air. Has anyone had this happen? Thanks for the responses.

 

It's actually normal. Sounds like a "pssffftt." It's even more pronounced with an open element. Once you do the SE or other high flow air cleaner you can hear it.

 

Thanks dawg. Appreciate the feedback.
