Hello from Nevada!

Just joined the forum to try to get some help with diagnosing an issue on my 2011 Versys 650. Glad to be here!

Lurching when constant throttle & off

So I'm new to wrenching on motorcycles but I'm determined to get this issue figured out and my bike running normally again. I'm new to some of the terminology so I may have to ask for clarification

Background:
The lurching began after I re-installed my wheels after getting Road 5's put on, which are pretty freaking sweet tires. The lurching feels like the bike is getting pushed backwards, then forwards and makes my body jump up and down like riding on a really bumpy road, if that makes any sense.

What I've done:
  1. Put motorcycle on rear paddock stand and spun wheel to find the tightest spot and adjusted slack to ~30mm and verified alignment on both sides. I've adjusted the slack 3 times in the past ~2000 miles, there were times I could hear the chain slap the swing arm when engine braking. The lurching got better after each chain adjustment, but was definitely still present.
  2. Measured 8 chain links at a time at the same location on different spots of the chain. Everything was the same except one measurement which was about 1/16" longer.
  3. Adjusted throttle as it was pretty loose when I first got the bike.

What I've noticed:
  1. The bike lurches the most in lower gears/speeds, primarily 1-3, but I can feel it at highway speeds (~80 mph).
  2. The lurching goes away if I engage the clutch, but I can feel/hear some sort of friction coming from the rear sprocket. I can also feel the friction feeling in the pegs when I'm using the rear brake.
  3. Lurches when holding throttle constant, if I let off the throttle it gets worse.

At this point I'm not sure what it is, if it's actually the chain or if it's something else. I definitely feel something coming from the rear sprocket that happens once-per-revolution so maybe there's a dead link?

I would really appreciate some input on what I can try next to get this issue resolved! Thanks!

The uneven chain slack would have been my 1st checkpoint too.

Warped disk brake (rear or front) causing some friction, would be my second guess.
In 3 tests, one per caliper, you press each caliper with your foot to create some space between the pads and the disk, then go rolling.
(of course, be ready to brake with rear if you made slack on the front, and vice versa...; that's the main reason to not press all 3 calipers!!!).

I'll check this tomorrow, determined to get this figured out!

Whats the KM/Miles on the chain?

All this happened after you replace the back tire and its better to run a check on installation if anything is not done properly.

Assume not ABS

First is this ABS, I asumed not. So the rear wheel is tricky to install, and easy to mix up the spacers. The rear brake has a guide that needs to be slid into on the swing arm. As to alignment, never use the marks on the swing arm, if you are lucky, they may be close, but they could be off by 1 slot between sides. Lots of threads on this. Second thing is it is very important to have the throttle cables adjusted properly, there is a push and pull cable , view the manual for setting these or follow posts on this. One thing I would look at is getting the wire harness for measuring the main and sub throttle voltages. In 2007 Invader posted tweaking the TPS, in 2015 I went and used my Kawasaki harness and measured the voltages, surprisingly, just tightening the Torks screw can throw the reading off . When I tweaked my 07 versys, I was about to sell it because of poor engine response after 2 months of owning it, after tweaking the TPS , you would have had to offer me more money than I payed for it originally to sell it, it made that much difference.
