wobble during hard cornering
I have experiance a sort of walking/wobble motion during hard cornering. It "seems" to be more in the left turns than the right turns. But not by much. What are the fixes if any?

Mine was due to air pressure. Bumped my front tire to 36psi instead of the recommended 30 and the wobble was gone.

Could you expand on what you meant by "hard cornering"?

Tire wear and profile, head bearings, wheel bearings, swingarm, tire pressure, fork springs/oil, shocks, triple tree, alignment...

I'm thinkin asphalt rather than sand?
Seriously, I would definitely try air pressure first, but then next would be fork oil and rear shock adjustment. I like to run over a good pothole and feel front to back to get the hit even.
If the front is stiff and the back is soft I adjust the rear stiffness until it's a good thump/thump, and so far that has always worked out good for me on all my bikes (at least the ones with so little adjustment as these). Cartridges require more adjustment, but the feel front to back still needs to be somewhat equal.
You may also get some good help from John's 7 pages of suspension sticky.
Mine is lowered to 11" shocks in the rear, so hard cornering is not much of an option unless I'm in dirt, and personally I don't see any use in trying to make a 30's era scooter into much more than it is. I figure there are limitations to speed that I reach long before the suspension is in full play.

Again mine was the air pressure. I found it would get worse as I accelerated hard through the curve to the point of having to back off the throttle because of the head shake.
