Hi everyone! I have a 2013 freeride with the 800 exec. I pulled the exhaust valves out and noticed these marks on the metal parts. Any ideas what would cause this?

Upon closer look, the rave valve hit the piston causing the mark in the valve. Time to replace the pistons. Good times.

Putting new valves and guides in. Now new pistons as well. The guy before me bought a used gauge cluster so I'm unsure of the mileage. My guess would be about 5K miles.
