It works !!!
Here is the final look with turn signals mounted
These are the brackets that I made to hold the screen and to reposition the turn signals, the curved bit is for clearing the front brake pipe :
Still need to paint them black and paint the screw heads black also
As for performance, this weekend we had 15ºC and a sunny day and so I went for a spin , and while it's no Goldwing,it does work, you feel much less wind pressure on the chest area, and the stream flow of air is just a bit to high for me (i'm about 180 cm tall) so I think I will lower it and/or tilt it back a bit
As for now i'm happy with it, and looking at the bike without
the screen now, seams strange .
