My bike was getting 90 PSI compression tests. Decide to take my first 2-stroke apart so here's some pictures of my the cylinder and the piston. Looks like a pretty good scratch right above the man exhaust port. Please take a look at the pictures and tell me what you guys think. I'd like to get this fixed as soon as possible. Where do I send it for repairs and nikasil?

1980mcneil:
Of course I'm having a tough time uploading the pictures. Suffice it to say I could still use recommendations on getting replated. I'm in Seattle so a reputable place closer to home might be a little better. I've heard a lot of people mentioned millennium. That's the first company that popped into my head. The hell maybe somebody local is really good and I could just drop it off. Looks like somebody's done some porting on the cylinder. No idea if it's a decent job but honestly this go around I'm not even that concerned about getting the extra power. I just want to get back on the trail I have a Wiseco piston already bought so I mostly looking for a quick turnaround. Any advice would be great. I'll try to get some pictures up after I clean up and get inside the computer. Maybe I'll have more luck than on my phone

Pics?

I took those while taking the cylinder apart.  I'm gonna go down and get some closer pics if I can.  there are a couple brown spots, not sure if that is the plating wearing away or just stained.  Pretty bad scratch as well in that first pic.  I assume that dooms it from not getting re-coated.  Let me know if you want to see specific spots.
