521cc cub motor, 23cc super cub domes, 50/50 93 octane-110 octane Turbo Blue mixed at 32:1 Maxima Formula K2, +4 timing, and unfortunately still the FMF golds that came on the bike when I got it. Probably wouldn’t hurt to get a couple sizes up and down from those too right? Sent from my iPad using Tapatalk
