Tuning with jets, Power valves and an O2 guage

IMO, unless you limit the amount of advance and delay when it all comes in (which I see no evidence of you doing yet) I don't think you will make any headway now. I think the cam change certainly went the right way with cylinder pressure, don't you? I've certainly seen engines with around the same cranking pressure run on pump gas. I think yours can too. You're just gonna have to find the right combination. I wish we were closer. I'd ride over and help you with it.
