Highwayman Air Scoop

Preliminary testing of adding a scoop to the side of the engine showed a drop in temperature. Which makes sense, the faster you go the more air gets pushed over the cylinder head.

At some time in the 80's someone had the same idea but it may have just been for looks

To test it properly a test jig with air speed measuring device was made up in the cowl... it is yet to be put into practice...
