So the sport screen in the high position is at ~ 53 degrees.
And there is insufficient clearance from the headlight/fairing to allow theoretically optimal airflow smoothness.
A bracket will be made between each pair of the upper and lower windscreen attachment sites with the brackets extending beyond the upper attachment sites.
Then a pair of secondary brackets will be attached to each primary bracket.
The lower pair will extend at a 90 degree angle.
To move the screen forward 2 inches, the lower secondary brackets will be located 1.4 inches from each windscreen attachment site creating right triangles with 2x2=4 and 1.4x1.4=2 and 1.4x1.4=2 such that the hypotenuse squared equals the sum of the two legs squared.
To achieve an attitude of 60 degrees, the upper secondary brackets will have longer lengths to move the upper screen forward relative to the lower screen. The lengths will be determined after attaching the lower screen brackets to the frame based, moveable, screen attachment arms.
Bolts and nuts will secure the plywood to the screen attachment sites and the primary and secondary brackets to each other (allowing for initial adjustment of the prototype as needed), and the secondary brackets to the frame based, moveable, screen attachment arms with the OEM, BMW pop-in plastic pins.
The initial prototype will be of thin plywood pieces.
Testing results to follow....
