Thanks.
It wont show up in a pic Otto. i can only barely see it. I can and feel it if i run my hand over it.
My friends have gsx600 and R6, they have the same problem.
Maybe they are running under pressure?
I know i had low air in my tires early this summer. Hopefully thats all it is.
I am in need of a new rear, i may as well get a front tire too. i am going to try the Michelin Road 2's.Sport tour. they are a dual compound tire. softer on the side than the center.
I found the Powers wore out to quick. i only have about 4500 moles on the rear. No burnouts either.
The road tires are made for heavier bikes too , so that may help.

It doesn't take long to cause noticeable wear if the tire is underinflated. One 120 mile ride can do it.

I get around 15k or more on mine. I liked the Roadrunner (AM20/21) but that was discontinued this last year. The replacement is the "Road Rider" (AM26) The best is the venom (AM41/42) but it is a little more money. Yes and they also have tires that are quite a bit more expensive, but I find them a waste. I run plenty of ponies in my bikes and ride quite " Sportingly", and I have never had problems with the less expensive ones. Made in U.K.It is very surprising, how they can get low without u knowing.

I just heard back from another rider. he said that cupping can come from improper suspension damping adjustment.
There is a lot of info to read at this site. i have not read it as yet, but thought i would pass it on.
