When i open my throttle 100%, the needle comes up so far that it falls out of the jet. Ive tried adjusting the throttle cable with no results, there is a Torx screw that limits the amount you can twist it, but its not adjustable for some reason. Any suggestions? Its an 07 crf450 btw Also, the needle i currently have is the NJYR, but for some reason i cant find it in any online microfische. Is this what everybody else has in their bike? (assuming its stock).
