Rear axle clunk (S2R800)

[XJBaylor]

I just bought a 2006 S2R800, and noticed something odd. When I roll the bike there is a clunking sound coming from the rear axle. It happens about every 1/8th of a rotation. It sounds almost rubbery, as if the sound is being heard through the tire. Has anyone experienced this? Any clue as to what causes it?

Sounds like a cush drive rubber is floating around inside the wheel hub.

It's an S2R.  Can't be a cush drive in the wheel.

Usually when the cush backs out on a S*R, it hits the eccentric adjuster.

I looked at the pdf file...

you're right.

Could it be just bad cush drive rubbers?

We'd need more information.

The OP would have to isolate where the sound is REALLY coming from, taking account that the sound may be resonating through other/multiple parts.

Get the bike up on a stand, this will make it easier to rock the wheel back and forth while you listen for the noise.
On the S*R's the cush drive is via elastomeric bushes in the sprocket, these have been known to shear, almost always when this happens the bush backs out and contacts the eccentric hub and grinds away the adjusting flange.
