Screw only governs idle to mid,then needle takes it from there
Your needle only works until just before WOT. At WOT it is all down to the main jet. Your bike will actually run ok even if you take out your main jet if you dont open the throttle all the way. It will flood in a second if you do.
It is quite interesting to do it just so you see where the needle gives out and the main jet takes over.
