Howdy, welcome from Montana

How does the brake disc line up?

Removed both shocks. No discernible movement. I didn't ride this bike much. Rode it 20 miles home and a few shorter rides around home. Hard to imagine that the chain was that far out of alignment. As stated, I have not had the rear wheel off. Neither sprocket is chewed up. I used Rays spacer with the oring when I fixed the trans leak. Trans sprocket is not dished. Not rubbing the trans. Wheel is slightly off center. Moving to line up sprockets would move it further out of center.

Yes unhook the shocks and see if there is side to side play.  Mine were in terrible shape, as were the neck bearings.

I have never had the rear wheel off. I did have issues fitting an inner primary, but I actually moved the trans out. Sportster sprocket?

It's really unlikely, but since you're right there, check the swing arm to insure there is no side to side play. Those swing arms are attached by a pair of Timken bearings. Usually if anything they get really tight from lack of maintenance. But if a bearing were to fall apart with age (42 years old) you might see some play.

I didn't change either. I have not had the rear wheel off. I did loosen the axle to adjust the chain.

Did you just change rear sprocket

I have S&S crank so hopefully no issues with it. B motor 01 .

    very important IMO 

That combination would certainly shorten its life!
