First Time I noticed this. The chain is wearing on the case. please click on the link below.

I did have my first chain break on me, I suppose that's when this could have happened, when it derailed. Chain didn't catch on anything, just fell to the ground. To me, it looks more like a slight constant rubbing. The groove gets deeper towards the bottom. There is also a nick on the fin. (upper left of pic)
I have a 12 tooth front sprocket instead of the stock 13 (1/10'' shorter) and a DID O-Ring chain (appx 1/10" wider than stock). I have checked the clearance several times over the last year, and it always looked good. I use the reference marks on the swingarm , and they are good. I measured them with the swingarm off. I have also measured from the swingarm bolt to the axle after using the reference marks, and they were both good. This kinda has me stumped, and I'm thinking I really can't ride it like this until I figure out what's going on. When I put the current sprocket and chain on the shaft right now, I can't get it to come close to the case. It looks like plenty of clearance. Is it supposed to slop around much when running?
I also pay attention to the chain tension. The chain has some wear marks on the top of the links, (shiny spots) but it's more on the outside than the inside (inside of chain would contact the case), so I chalk that up to contact with the chain guide. I have kept the stock guards in place.
Has anyone noticed this on their bike? Is the case any thicker at this point?
The only thing I noticed was once, the rear axle was not butted up against the tensioner bolt on the right side of the bike.
At this point, the only idea I have is to go back to stock, use a permanant marker on the gooves, and check to see if it's still getting worn.
Any ideas/feedback greatly appreciated.
Thanks
Joe Chief
