Soo,, I had it..

You might be right Justin. It's odd that there is some grinding noise coming from my drum when I roll my bike, but it is on one side because I get free rotation until i hit that patch. An idea what ot coud be? I just got a stand, so im going to take it apart tomorrow.

Oldfeller, yes my rear tire was not wearing evenly radially. They guys at the shop i took it to didn't see any problems  with the truing of my wheel. One thought  i was doing  burnouts on it. When I troubleshoot the rear brake grinding tomorrow, ill check the truness with zipties attached to the swingarm.
