[QUOTE="jimt_yz400, post: 162952, member: 21081"] Rich, After re-reading your reply, you recommended the best bang for your buck is oxgenated race fuel with "sharp" jetting. What do you recommend ffor race fuel? I've tried the Unocal 110 octane and I attempted to jet it but I didn't get what I thought was any agains in performace. The fuel that I was using was NOT oygenated so I gather that would have an effect. I'll try to find the fuel that you recommend if I can find it and so long as it's not terribley expensive (I'm kinda immune to $10/gal fuel!!). Thx!! [/QUOTE]
