I've been running 32:1 in my GFs '01 RM80 and it feels too boggy for me. I'm going to try some 40:1 and see if that clears it up. It just doesn't have the snap it should. Might be a jetting issue, I'll get into that if I can't clear it up with the premix. Thing I'd ask to see what the general consensus was on the ratio for these bikes...so, whatcha running? We ride woods, no MX. Thanks.
