A few weeks ago, my Rebel 250 blew a piston, allowing the piston rod to beat on the top of the cylinder and the valves.
There's some scarring there now, as well as a jagged protrusion or two. What are my options for repairing this scarring?
Can I hone it down to simply get rid of the jagged bits, then brush it out?
Or should I replace the entire cylinder head?
Here's an image of what I'm working with. It's not great, but the damaged head is on the top.
