The lower section is attached to the upper with gen1 type screws, there is just tape put on top of it.
Yes, the front is very light and goes left and right.
I had similar problems myself one time using different fairing and the cause was rear being too low compared to front and jacking the rear up solved it completely, but no help in this one.
I`m afraid we don`t have pictures of it in higher speed.
He installed there also the side panels, but they blew off right at the beginning, so there is lots of air coming between the frame and fairing.
I can`t tell about the weight distribution at this point, it was second try, the first one was in bad head and sidewind and we just thought it didn`t work then, but this time it was tailwind and it was even worse.
We tried different nose heights and it didn`t help either. Do they slam the nose into the fender, no free space left at all ?
