You're right, I removed the clocks and routed my power cable up between the clocks and headlight.
I can still use the screen adjustment without issues but I have my screen in its highest position all the time so I have no idea if frequent movement of the screen would cause future problems..
I used plenty of cable ties to hold down the power cable in as many places as possible so hopefully it shouldn't move but the only part I'm not happy with is the point where the cable leaves the clock surround, its fine but while riding it does move slightly because of the slack left in it so I don't stress the cable, part of me is tempted to drill a hole so I can add one last cable tie to make sure it stays out of the screen adjustment mechanism.
