Squeaking/chirping/whistling noise
2014 Ultra stage 4, 40k on the clock.
Im at a loss here. Ive checked the exhaust brackets, and motor mounts. Cant quite pinpoint the noise. Seems to be coming from the primary or top end. The noise raises and lowers with the throttle. No change if I pull in the clutch. Anyone have this issue before?
I dont want to tear into things I dont need to, but something is wrong here.

To me, it sounds like a lifter that won't pump up. Are they original lifters?
May need to raise the pushrod tubes and rotate the engine to get each lifter at the low spot on the cam and check for slack in the pushrods.

Your description sounds like the squeak is timed with your wheel rotation nor your RPM's maybe? If so I found that to be caused by a defect in my drive belt... unless your throttle/squeak is when your bike is sitting still? Then a simple compression leak can cause a squeak...

Compensater bolt loose or warn comp, primary chain loose or bad adjuster?
Take outer primary cover off and have a look.
Headers on tight? Almost sounds like it could be an air leak exhaust or intake.
Good luck hope you find the issue and it is an easy fix.
