You can also mount it behind the screen, onto the silver trim panel that covers the back of the clocks. You'd get a better POV from there and less weathering and you can keep an eye on it....
I made up a simple ram mount on the clutch reservoir lid. Drilled two holes in a spare lid, tapped them and used a little blue loctite to make sure no clutch fluid gets out. It's been fine for many miles.
