OK, I screwed up by deciding to replace my chain. My rear tire had to be replaced so I removed the chain as well. (At 5k, my old chain looks as good as the new one, even the o-rings. At least I have a good spare.) It all went back together very easily, but I am not satisfied with the chain adjustment. I followed the procedure in my Ducati service manual, lining up the notches on the swingarm, but this bound the chain and you could see it was out of alignment. I did this several times with the same result. I then pulled the tire back to tension the chain and tightened the axle nut a bit, followed by the chain adjustment bolts. This aligned the chain and sprockets. It also allowed the chain to roll very easily. My alignment marks are about 1 1/2 marks off from one side to the other. My left side marks start big in the front and decrease in size, the right side is opposite of that. Any ideas or help from the pros?
