Stuck to the screen is better. Need to be more angular to pick up the lines of the bike. Currently foul the bars on full screen extension but that's easily sorted Thoughts appreciated.
Have a look at the V4 screen Winglets, they work and are the right shape. No idea if they could be fitted to your bike as the V4 has a four bolt screen.
That looks proper crap and how would you permanently fit them there? Why not fit them inside the the fairing? Take a look at Eagle Screens winglets and you'll get the idea.
I think Iconic Engineering in Grantham do some plexiglass winglets, it might save you a lot of messing around.
Yeah it's not meant to look good made out of cardboard! Just playing around with some ideas that's all. Have looked at Eagle Screens, nothing for the DVT unfortunately.
