well after being very mad about my bikes very poor throttle response and jetting and having my bike cut out on a lip of a triple at supercross track and damn near breaking my anlkes from a very nice case i decided to send my carb to zipty like everyone seems to recommened doing. well i just got my carb back and got my bike all put back together all i can say is wow! this thing has such good response its nuts. i knew it would be good but not this good. i rode it down the street for now and there is a very noticable difference! ill write some more after i ride it at a track tommarow. im so glad i spent the money on this!
