Right on glad you figured it out. Do you have the internal bearing sleeve for  that carrier? I have seen that part not installed on many bikes, including a basket case Irecently  picked up.

I had one GS750 rear wheel where the spacer between hub and sprocket carrier was missing and the wheel bearings were probably 1 mile or less from completely collapsing. The cages were distorted and snapped and balls were far from round.  The PO dodged a bullet there.

That spacer MUST be in place between the sprocket carrier and wheel bearing.

Just had another thought.

I wonder if this time you swapped the left and right spacers over without realizing it....

Thats crazy how people can leave a spacer out like that, I did realize it goes in both ways but is slightly longer on one side, the book had no reference for which way it goes in but maybe that was the problem?

It's very very common to be missing on Kawasaki's, the sleeve fit is much 'looser' than most other manufacturers use so they fall out when carrier is removed (or stay on wheel hub then fall on floor when wheel is moved) It isn't a parallel spacer but has a tihnwall extension to fit into bearing reducing inner diameter
When I worked in Honda/Triumph dealer we kept a few in stock  as they were almost almost missing when bikes came in for tyre changes or wheel bearing replacement because bearing 'just broke up'
 One guy rode from Germany  to airbase in South Wales (about 700 miles) with rear wheel loose about 500
