Cracked piston, what to do next.

Ok, so I got this Yamaha YG1 a bit ago. It ran fine, but it was really easy to kick over. Wasn’t sure why, so cracked open the cylinder head. There is a chunk taken right out of the piston roughly the size of the top of a fingernail. Cylinder has minor scratches, but not the worst. What action should I take?
