Rear Wheel Spacers

Well, I'm a little concerned.
My rear wheel does not spin freely when the axle bolt is torqued to spec.
Loosened up a little, it's better, but ???
I'm trying to figure out what is up, and I notice on the parts diagram, the spacers on each side have different part numbers.
I believe both of mine are the same, or at least appear to be.
My plan now is to pull the wheel again and measure them -
I'm getting conflicting information, Partzilla has one diagram, factory manual has another, slight differences, somewhat annoying, but typical of these old bikes.
Far better than trying to match up old Kawasaki triple parts!
Any input appreciated, thanks in advance

Is it possible the only difference is 1mm in width?

Maybe I have them reversed....

Figured it out of difference

40mm vs 42mm
Both I'd 20mm and are 13mm wide

Disassembled, everything seem in order.

I'm wondering if it's possible the wheel bearings have been replaced with aftermarket item that may be slightly thinner.

It's all back together, didn't tighten the axle nut to torque.
Wheel spins, but not like a bicycle.

Are you spinning it with all the dust seals in place?  With the brake caliper mounted?

Brake pad drag will make a big difference.  The dust seals (both the ones installed to protect the bearings and the ones built into the bearings will make a difference too.

Make absolutely certain that you also have BOTH of the other spacers installed within the wheel assembly.

One goes inside the rear wheel itself and rides in between both wheel bearings.
The other one goes between the cush-drive and the wheel.

If either of these are not installed it will put a side-load on the bearings when tightened up.

My memory screws with me, and I've had this problem before.

Backing off from full torque seems to fix the problem.

Seemed to be more than brake drag, and I do need to replace the dust seals.

Once I back off the torque, all seems to be fine.

I'm about to find out, heading out for a short rideabout.

They're good. I did remove the cushions when I had the new tire mounted and checked the spacers, ironically, they seem AOK.

Backed off on the axle torque a bit, all seems good.

Steve - curious - is yours the stock rear wheel?  Or a swapped one?
