Topic: Rear wheel help

[mycb750k6]

I put my rear wheel on my CB750 and spun it on the center stand. The hub, rim and tire all appear to be true. But the sprocket hub where the sprocket is bolted on appears to have a wiggle. The sprocket doesn't rotate true and the reason is the hub sticks out a little more on one side of the center than the other. How does this happen and how can I fix it? Did I explain that right?

Just a question but are you sure it is the hub? Maybe the sprocket is warped?

[mycb750k6]

That was my first thought too but as I looked closer at the hub, I could see it protrude more on one side than the other which resulted in making the sprocket appear to be warped. But the root cause is in the hub. I would say it sticks out a 1/16" of an inch where it should be even with the hub all the way around.

It might not be pushed all the way into the cush drive.
The sprocket assembly floats in a a set of rubber cush drive thingy-doodles.  The rubber might be old/warped, or just not in all the way.

 get into the strange stuff... stick it in a bit further..    


 sorry..., had to do it..

 Its just not seated, probably fall in place after it goes round a few times... sometimes I get a bit of oil off the dipstick and put a light smear on the leading edges..

It is the cush drive rubbers. Spray some windex on them and get it lined up well and give it a few whacks with a rubber mallet or something padded. If the did not sit tightly in there you get a lurch every time you let out the clutch.

OK I believe you. I'm going to do it now, And thank you!

Yes I think that's the likely issue as well. But wondering did you tighten down the axle? Seems to me that would set the drive plate into its rubbers. Though its always better to set it first, the axle should not be doing that duty. Just curious.

Here's the problem. The one I pulled out on the left and the replacement I put in on the right. It was just bent over and not through the hole to hold it. See that's what I mean. I've got to go through everything. There's no way this didn't screw up the PO's sprockets.
