I'm gonna see if it's in service limit. Remember it's not my bike. I'll give the owner the option on what he desires. I just put it together! I just prefer wisco personally

just make sure you tell the owner, if the connecting rod is bad ?, he'll just waste money just by doing a top end, telling ya, it won't last long at all, and he will be right back to where he is now.

Gonna get a second opinion from a local mechanic. Piston wise should I go a 91mm or a 91.50mm just to be safe?

Your machinist will be able to tell you that. Id he takes say 0.90mm out and there is still deep gouges you'll probably need to go bigger. But I aint no machinist.

Make sure your machinist measures for more than just the next oversize diameter. Taper and out of round conditions are just as bad and can force you to bore to an even bigger oversize.

Kinda hard to see but that's what I mean when the piston is crooked in the cylinder.

can mean it is out of round ?, bored crooked ?, connecting rod bad ?, wrist pin on piston is bad ?, any of these. makes no difference, cylinder has to be fixed, as well as connecting rod checked.

Looks like it's been pretty hot, I'll bet the rod it toast...
