So my 2015 sportster 883 with 16k miles, started making a a weird noise after accelerating above 2500rpm’s. I thought it was the clutch brass springs that broke. Today I opened her up and found nothing wrong in there. Oil when drained was clean, no metal shavings. Inside everything looked new, even the whole clutch pack. I replaced the clutch anyways with an Energy1 performance clutch. Took it for a test drive and the noise is still there. Took a video, any help is appreciated.

Checked it twice cold and its at 1/2 inch play cold, and yeah it does it in neutral too. Its like a winding noise and gets louder as the rpm's increase. It doesn't sound at idle at all. The pic was from me inspecting and changing the clutch.

Checked it and it’s all good. If you meant the bracket that holds the exhaust to the rear cyl head. Also checked the exhaust pipe covers, all snug good.
