Larry bro, ive ran it on both 91 and 110 already.. and running it on 110 makes a huge difference, the bike gets like possessed and just rips.. Scary fast. This last time I took it out I was at a dry lake bed. And I ran it on 91 and it was not the same.. so 110 gives me a big difference in power. Thanks Tricked Carbine, you understood me pretty good. Now jetting, you guys say its pretty easy. Ive never tried working on them. But when I do I will no doubt post a forum about it. BHQ fucken rocks
