Default Tranny clunk

I am about to reset my clutch for about the 5th time these last two weeks. Set the clutch cold with about 1/2 turn from bottom. I think I've got this right, maybe.
I am still getting clunks not only at 1st, but in 2nd, 3rd, 4th mostly when downshifting. Hard clunks.
My bike is an 07 RKC without an ISP.
I am wondering if there could be something out of alignment with the tranny linkage?
Any thoughts appreciated.
Enough redline in primary, cable completely loose, cool bike, bottom means where clutch first bottoms. 23,000 on bike.

No responses? I reset clutch just now. Found about 1/4 turn in to give 1/2 turn from seat. Will see in morning.

Possible your primary chain adjuster is not ratcheting up.

The clunking you hear is normal As far as I know all the harleys have it. Not an issue. I know several people who own them and they all do it. Including mine.

It's a Harley they all clunk. Ride a Buddy's or go to the dealer and try one, you'll see it's normal.

Some say that ATF softens the "clunk". I dunno, never had a problem with mine.

I went to Mobil 1 V-Twin 20/50 in the primary and it's smoother than with the dino oil or the ATF.

You might pull your clutch plates and give them a good looksee as you rub them down to check for defects. It helped mine. I might have had a few plates sticking a bit.

I do run redline, and have been adjusting clutchs for many moons. Problem is I can probably top end an engine easier then adjusting a clutch.
Boomer you may have given me some insight. I've readjusted and gave a little ride early this morning. It's better, now for a longer ride.
Thanks.
