Have someone (with upper body strength) hold your bike perfectly straight up & down. Grab ahold of the rear tire and try to "wiggle" it forcefully. Have your mesomorphic buddy keep the bars still as best they can. Have them lock the front brake too.
Does the wheel move laterally at all? It shouldn't at all. You'll be checking your rear wheel bearings and your swingarm bearings when you do this. Don't be surprised if you see movement at the rear tire edge.

That will also check the motor mounts, but you should check them anyway. Have you set the FXDX suspension damping? You need to set the front at the top and bottom of the fork tubes, the rear just at the top. When check the fork oil, think about changing it.

If you just got a new tire what kind did you get and is it a radial? I just went to an Avon Storm 3D. I went a tire size wider to learn that I now have a wobble. I should have just stuck to Avons recommendation especially with radials. The Max weight for this tire is 805 lbs, but the one Avon recommends for the factory size is 963. I didn't pay attention to the load rating and just assumed the weight was good enough. I've had a shitty radial on the rear before and had the wobbles. Went back to the stock Bias rear and it went away. Trying to find the right radial sucks ***. Next ride season I'll buy the recommended rear radial from Avon and just deal with this one the rest of the season because winter is not far away. Put the rear tire at max pressure and see if it makes a difference. If it does it's probably the tire, so double check the load rating on that new tire.

I also bought this mount. One day I'll get the rear spruthe stabilizer or true track to finish it up.

I installed one of those a couple month's back, went on a 2k mile trip to Yellowstone loaded for travel and wife on back. rode some curvy roads and some 90mph freeway speeds. did notice better stability even when riding in ruts. vibration not much different although was never bothered by that. they are easy to install, with a lift and scissor jack, took about 45min. for me, was a worthwhile purchase.
