If kevin raised the exaust port at all the compression is going to be less than stock with 22cc domes. If heleft it, your going to have stock compression. No need for race gas at 125psi. I would definitely run way more compression in a trail bike than what your running. I recommend at least 165 psi. Jetting for the setup you listed would be 190 main, dek needle, clip in middle, 42 pilot jet, af screw 1.5 turns out. Thats a starting point.
