[QUOTE="Micahdawg, post: 1168279, member: 21668"] VP Import is 120 octane. I think VP NO2 is close to 120, and maybe C23? Is 190 high compression? What's the bike supposed to have. I think 93 octane is good to 190 psi, so even C12 would be overkill. I'd use straight VP Motorsport (101) or a 50/50 blend of C12/93 octane. I've got 250 psi and run straight C12 at 32:1. I can run as little as 99 octane without breaking anything, but it pings badly at idle. At 93, the piston breaks. [/QUOTE]
