Tire bead seat is also my guess, having experience with this problem after having a Pirelli installed on front. Riding at say... 30-40 mph and looking down at the wheel over the handle bars, rim was spinning true and straight but the tire had a wobble to it. I needed to reseat the bead and go about 15# over max pressure to do so. Had to maintain maximum pressure all the time with this tire or it would start to get out of wack again, maybe a slight defect or just a shitty tire. I will never buy a Pirelli again... Now I'm a Michelin man

As far as balance goes... have your Indy install Dyna Beads in both wheels, you won't regret that at all.

From experience I will tell you this. If balance and tire pressure are good. I would ride that tire for about 500 and I will take a bet that the wobble will disappear.
I have gone through this twice on 2 bikes after a front tire change. Went down the checklist and found nothing wrong. My Harley dealer service manager stated to ride the bike and let him know. After 500 miles it cleared up. He tells me this happens with some new tires and the belts in the tire need to seat/cure. It took care of both bikes I had it happen to.

Before the tire replacement the bike would cruise without any problems at 100 mph. According to the speedo...
I live in California and keeping up with traffic is the law...
The wobble isn't a shake. The frame will go one way and the forks the other. Think of it as what your front does if you were to weave in between cones at a slow speed. If I put some drag on the front brakes it will straighten out but return immediatly when I release the brakes. It began to wobble as soon as I got on the freeway on my wy home from thje bike shop.

Details on the tire change.
Tire replaced with HD Dunlop stock size.
Bearings replaced.
New wheel seals.
balancing took no weights.
New valve stem and pressure is good.
Rotation is correct.
Brakes are good.
Fork oil has less than 3,000 miles.
Theres no "slop" in any of the fasteners/moving parts.
Everything looks correct and I'm not sure where else to look.
Returning it to the shop is my last resort.

Do any of you guys have any suggestions on where to begin on the diagnosis?
Thanks in advance.

Any resolution to your shake/wobble? Update?

Hi. I own the same, exact bike! Love the look of yours and, want to do the detachable tour pack. What did you have to buy or, do to get the rear of yours to look like it does? Also, what seat is that and, what has to be done to mount to rear fender instead of to the original tour pack rack? Any help, insight or, pics would be greatly appreciated

I called the owner of the shop and he gave me the run around so I wont be returning my bike there. The oil that he "changed" was just as dark as it was when I dropped it off.......

I bought what I needed to check my end play however when I went to put it up on my motorcycle jack the bottle jack had nothing left to give. I wasted about three hours of my time/a bottle of fluid taking it apart, cleaning it, and refreshing the seals. It didn't return to its former glory so now it is the base/weight with weels keeping my bandsaw upright and mobile. Twenty something years as a motorcycle jack.... It was time for a demotion. We never worked well together anayway.

Moving foward I am going to pick up a new jack hopefully this weekend. Then I will start with diagnosis. Going to follow through with all of your suggestions. BTW thank you everyone for your support.

They replaced my wheel bearings because the old ones were SMOKED!!! You guys probably already figured that out frm the picture.

JMB19 What you want are Harley dealer part #s53376-97 and 53422-97 to get rid of the tour pack. Around $100 and you will have to adjust because the mounting nut that I'm pointing to is on the other hole if I remember correctly. Its an easy mod though. My seat is a LE PERA SMOOTH FULL LENGTH LPL-867. I paid around $300 for it and just incase you were wondering my dash is not correct for the bike. Thats why the seat overlaps it. Couldn't stand the CB dash. Your back fender should already have the bolt hole for the seat. If you need some more detailed pics let me know and I will do my best to get them.
