hi guys. sorry to be bringing up the subject of jetting again but couldnt find this covered in any threads. i have a 96 650L with daves mods, de-smogged, big gun pipe. after carrying out daves mods the bike wont accept full throttle, it just dies. runs fine everywhere else but as soon as you hit wide open, zip. i have tried messing around with different needle shimming (up, down and sideways) but to no avail. anyone got any ideas?
