First, do not use octane booster. It's not consistant, and will lean you out.
Second, what oil pump? Cheetah's do not use oil pumps. You pre-mix.
To get the compression low enough for straight 93, you'd need somewhere between 28cc and 30cc domes, considering your timing and elevation. lt1bird's Cheetah PV 535 is in a streetbike. His has 27cc domes, and 0 timing. I believe he's using straight 110, but could probably get away with mixing 50/50. My Cheetah PV 535 has 25cc domes, +7 timing, and only runs on 110 octane. You need to explain more about your motor, and give your elevation, to really be able to tell you where to start.
