ok, ive done the jetting, and needle stuff, but i dont know where the air fuel mix screw is, and if i find it i dont know that i need to mess with it any. can somebody tell me where to find this sucker? you can see what im running in my signature, it seems to be just pretty good,, once warmed up it raps fast and runs good, on the TT track im holeshotting most of the others and all out its great. but im wondering if maybe there is some more in there that im not getting out. The aftermarket pipe (aaen) is on the way soon as i get some $$ so help in tuning is appreciated.
