thanks differntstrokes that helps heaps ay
max, looks like the airscrew is located behind the fuel line that goes in to the fuel bowl (right nipple/tubey looking thing to the right of the pen), should be on either side of the carb and you should be able to access it with the fairing off, you might have to remove the line or just push it out of the way. should be located just under your airbox by the looks of it too.
but looking at it again.. i cant be too sure
