96 Ktm 250 sx rebuild questions?

Hi guys I have a 96 Ktm 250sx it hasn't ran right since I got it. I took it to the dunes with a bunch of new jets and pilots knowing that the carb was jetted wrong. I'm currently running 172 main, 42 pilot, 2 turns out. But the bike won't hit power band? I took the reeds off and they were bent so I bent them back to see if that was the issue for a short term fix out at the dunes. Still no powerband. So when I got home I did a compression check and it's running 120psi is that to low to get powerband? I'm gunna tear the head and cylinder apart and replace gaskets, o'rings, piston, rings and wrist pin. Hopefully I'm within spec and don't have to have it coated. Any suggestions on brand? And anyone think that that compression should still hit powerband?
