The best routing depends on how far from the handlebar the fairing in placed, the type and position of the clipons, type and angle of the throttle and so on, In other words you will have to see what's best in your bike, to route the cables with the widest bends possible. FWIW in mine the cables go behind the fairing, under the tank. The carbs need to be mounted in a tilt to keep the cable adjusters from the fuel tappets.
