Rear wheel damper play

I just installed new sprockets, chain and tires. I locktited the rear sprocket last night and left it to dry overnight. Today I got home to check it out. Sprocket is rock solid, but i noticed that the rear damper moves in/out a few mm when I push on any one side of the sprocket, as in Im facing the wheel face to face and pushing down on the sprocket face, down towards the wheel. I assume this is what the damper is designed to do. No tolerance mentioned in SM. Does anyone know how to test this?

That's play in the cush drive. I don't think its too bad, I've never seen a cush drive go bad, even on a 1100 GSXR.
Cool.

By in and out do you mean along and parallel to the axle axis? If so you may have dropped the interbearing spacer from between the carrier and tha actual wheel. CHECK. If it is left out the bearings WILL collapse ( saw it happen right in front of me on a racetrack and I mean RIGHT in front...like 2 feet...Not pretty. The wheel doesn't fall out the the bike just slews all over the place.
I have done it myself when I didn't realize it had fallen out of the carrier. If you don't know what it looks like it is the spacer second on the left in the pic. It is supposed to be on the inside of the carrier bearing between the left wheel bearing and the carrier bearing. it fits into the carrier bearing.
If that is there, double check the bearings themselves. They could be dead. If that is the case the carrier will move but the wheel will not and the axle is clamped all the way through ( provided the spacers are all there.

This is difficult to explain. The wheel is off and down flat, parallel to the ground. If I lean over the top of it and push down on one side of the sprocket face, there's slight play. The damper and bearings have never been opened up. It may have been like this all along, but Im just fussing with it now.

Actually that is a perfectly fine description. Sounds like it is doing exactly what it should for that test.

good to know, thanks for the sanity check!
