I'm gonna say not normal . I'd pull the cover and take a peek. The adjuster may be stuck on a fresh notch but that's louder then I've ever heard. The last one I heard that loud was a cam chain whine due to worn inner tensioner.....
My 1995 Dyna had an HD auto tensioner. It had a "faint" whine. Never changed with wear, ATF or Formula plus fluid.
