They don't line up. Rear is dished about 1/2". Needs to come out about 3/8". Tire is pretty much centered in swingarm. 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?

Did you just change rear sprocket

Chippitt68

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

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.

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

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.

How does the brake disc line up?

Your side to side measurement can be suspect if one side is adjusted more forward cocking the wheel.  Having a rear wheel that "appears" to run off center in the fender (which is really just body panel), not chassis, is actually quite common and has been the subject of many conversations here.  My 2011 RGU runs about 1/4" to the left in the fender but on non rutted highway I can ride with no hands on cruise for ever if the road isn't too bendy or windy.

Have you compared the spacers?  Is it possible they have been installed flipped?

When the wheel comes off, I'll do that. The sprockets are fairly parallel according to string and straightedge. I assume I'll have issues with the rear break

Align brake then work on sprocket alignment
