I am going to suggest you had the wobble before but it was not apparent yet.
You then mix tire brands and also mount the rubber in the wrong direction I presume on the front. The rubber is intended to turn in one direction. How long, turning in the wrong direction before the rubber is ruined or at least contribute to a wobble?
In any event rubber turning the wrong way with better gripping and the wobble is made noticeable. The steering head was tightened and that did not help, Was that the problem, probably a part but not all.

Ah, that appreciably changes the story!

It seems you've done everything but check the change that started the problem. Namely the rear tire itself, and the mounting of the rear tire.

Start there. From tire pressure to load rating of this unknown tire.

Check the mounting of the rear tire, make sure things were put on right, and tight.

how about balance? I use RideOn and not the stick on lead weights. It could be a balance issue. Also, not to imply anything really bad, but I believe that Shinko are a pretty inexpensive tire and there could be a possibility you have a bad tire. One that has some internal "blemish". Again, not saying that's it, but ANY tire can have internal issues.

Thanks But only rode the the bike with the front tire the wrong way for about 10 miles to check if wobble was still there. I will take your suggestion about the rear and ask the dealer to check that

Took Bike back to HD dealer and Tech rechecked steering bearings and they are still tight and spot on. I asked about wheel alignment and he gave me a story about older touring models had that problem prior to 2004 and the things they had to fix it. He did say even thought tire are still new the rear tire (shicko) and the front Mich cmdr2 could be the different tires are causing the problem even though the tire patterns are similar. Ok maybe because I had a dunny on the front and rear with no problems but the rear was worn and I was coming up on a 400 mile ride soon so i got the cheaper rear tire so i could ride without fear. then I got the wobble. The front still had some life but I heard and read positive things about the Commander 2 tire being better than the dunlop I swear if I drop 160 plus install labor for a rear and I ride up to 70+ on the highway and i get the wobble....Goodbye Ultra and say hello to Roadglide.

Replaced the tires thinking they were the issue.New rear tire less than a month old(Shinko 777) and new front tire(Mich Cmdr)days old. Same problem. Checked brake pads and rotors were fine. Took to dealer and was diagnosed as steering nut needs to be adjusted($200) Also was told tire was mounted wrong meaning the tread direction was correct but the valve stem is on the left instead of the right. Was told not a safety issue but not standard. Since I took off the wheel and had another dealer install prior to this service, they were not going to correct it free of charge. No mention if the wheel bearings were bad. Ok, I get on the freeway and accel to about 80 83 mph the bike started the dancing again and roll off the throttle it got worse. Got home and took off wheel to take back to dealer to correct the tire mounting and will see what happens on a 150 mile ride... Any ideas or solutions to this problem??

Welcome to the pre- 2008 club. Start with checking fallaway. Then, add a bagger brace. If that doesn't help, replace cleve blocks. Sta-bo is a good option. Then, if that doesn't fix it, get new triple trees (CCE) and probably rear suspension as well. A huge chunk of the pre 2008 suffer from this (all I'd say as it's a design flaw). Most never notice it because they ride their Harley's like old ladies.

Personally, I'd trade it.

Stop messing around with mixed brands until you have a solution to your wobble! With a Dunlop and a Shinko you have two tyres from opposite ends of the spectrum - one as hard as nails, the other as soft as - well, very soft stuff! Create a sound datum from which you can analyse your problem, if you still have one. When your Shinkos are worn, replace them with your preferred brand, you have plenty of time to decide which one that should be.
