| I have recently fitted a complete set of bodywork. I agree with the advice given earlier.
I would fit the screen to the fairing first and then put the fairing on the bike and mark the mirror holes etc. The screen holds the "ears" of the fairing at the correct distance apart - if you drilled the mirror holes without the screen fitted the screen might not fit.
Be patient and don't rush it - as if you were having sex or drinking a nice Rioja........
