I have a Gustaffson 4" over screen for my bike. I mounted it up, ran it for a couple of days and then took it back off. Didn't work well for me at all- It rattled more (but I didn't put the bead around the edge), the wind was all wrong, and I ended up with even more weight on my wrists- which I did not want.
At the time, I had the stock clip-ons on the bike. I'm a bit more upright in position now, so it might be a better fit, but frankly, I like the lower fairing. If anyone wants to buy the taller screen, it's for sale cheap.
BTW- the design is not like the picture you have with the flip up at the end. The one I have is just overall taller- a bigger bubble.
Cheers,
Jason
