You can see some scoring on this piston to the right of the wrist pin. This is the left side of the engine, the side with the noticeable 'clank'.
I believe this to be caused by chrome flakes, but cannot say for sure. I have already purchased a new set of Gilardoni cylinders and pistons from MG cycle, so I wasn't too concerned with the condition of my old ones.
And one more point of interest is my small end bushings - particularly on the right side, which fell out under its own weight! Here you can see it inching its way out of the con rod. These are supposed to be a tight interference fit, so yeah - this is another bad sign.
