If your compresion is 11.5:1 or lower I know you would be fine with just 93.

Ive always had good results running a mix of pump and race gas even on stock machines....With your new motor work it should run very nicely.........

ummm no.......11:1 is the absolute highest being air-cooled....its still a good idea to run a mix at 11:1 though.
