If you are getting no change when adjusting,you are either on the wrong screw or your idle circuit is completely plugged. when you remove the idle mixture screw there should be a spring & o-ring on the screw.make sure you don't loose them.The mixture jet is pointed on the end.It should be set at 2 turns out to start than adjusted with the bike running.Jet should look like 3rd one in pic.
:cool:
