Kx pegger I think the camera flash makes the piston look worse, Everything was stock, bore, crank, with Pro X piston, plug has a nice brown color and everyone that has come through the shop and looked at it has come to the conclusion that the rod must of already had a stress fracture in it due to the inconsistent metal coloring at the break point. I replaced everything in this engine but the rod or crank and I had no history on it, But it all was in spec and no indication that it had any issues.
