Hey guys

I got a 1989 CR500 that I recently replaced the header o rings on and took a look at the cylinder. It runs great, doesn't feel down on power at all. I see no signs of detonation, the piston wash looks good but I see some dark lines on the wall. The hatching still looks good but these are concerning. They don't seem deep at all but I thought I would ask what you guys think?

Thanks!

Looks like dirt is getting in as the scratches seem to be on the intake side.
Check your air filter for leaks and also be sure your fuel is 100% clean.
