Oh man, I didn't even look close at your pictures at all. What happened to your poor pistons?
Well after 100's !!! of hours of stock bore / piston use, it finally put itself to sleep on September 6th 2008

Really I am surprised that it lasted as long as it did, in late 2007 the water pump gear took a shit, and caused some overheating, which cause the pistons to go brittle, then finally it broke after riding it in '08 ... I could tell that it was down on compression, which was the right hand cylinder (it took out the top ring). Then the left cylinder took out a chunk of the piston, finally causing it's demise.
