You're putting the cart before the horse. Just check the cush drive for now.

most drivability issues like that come down to chain or sprockets or cush drive wear, 20k on a chain and sprockets is pretty close to the limit of usuability.

A lot of riders replace the cush drive just like brake pads, chains, and sprockets. They don't show wear; I've taken ones apart that had 40k miles and they look fine; but when the new ones go in, the rear end tightens right up and things are better.

Do you have a centerstand? Get the rear wheel up and study the chain and sprocket as you rotate the wheel. Look for kinks in the chain, or places where the chain "rides up" on the sprocket. There's other possibilities, but the most likely place for your problem is in the drive line: front sprocket, chain, rear sprocket, cush drive, and axle alignment.

I've replaced the rubber cushions in the rear wheel with cuts of lean porterhouse steak that seemed to work ok. Only problem was being chased by dogs, and a strange craving for A1 Steak Sauce whenever it was time to gas up.

Port chops work too, but by some are considered "unclean".

Did you know Cheez Whiz makes a fine tire sealant? It's the original "Slime."

I've seen ancient ones that were like tiny triangular bricks, with hardly any slop in them - and I've seen ones that were only a few years old be nothin' but bits of rubber and black dust.

If the sprocket and wheel can be moved in opposite-directions by hand more than a tiny bit, it's probably the cush-rubbers. If they're "stuck together" and barely have any lash, but the wheel and driveline moves quite a bit with the bike in gear (but not running, obviously), the backlash is further-up in the line. Start with the front sprocket, and diagnose from there.

Thanks for the kind feedback ,

I forgot to mention one thing , I actually started to notice the problem only after I gave the chain and the rear sprocket a thorough cleaning.
So would this info narrow down certain possibilities ?

thanks again

Did you get the chain squeeky clean? It probably has no bearing on the issue.

So stopped by the shop today , and let the mechanic take a look at the chain and back wheel (drive) etc.
I mentioned the cush drive , but I put it on the lift and put it in gear , but when trying to move the tire with hands there was no slack at all.
Should the cush drive be taken out and inspected to be for sure , or is this enough to rule out the cush drive as being the problem.

He tightened the chain for me a bit , but I still feel a certain slack in the drive area when riding the bike.

Cush rubbers are probably good then.

Search elsewhere.

You're absolutely certain it wasn't there before, and not just that you've only gotten well-enough acquainted with the bike that you're just-now noticing it?

I say that, as some bikes have what seem (to those unused to them) to have an "excessive" amount of drivetrain-lash. The early FZ-6 comes immediately to mind (as I own one).
