There is an MRA screen spoiler attachment available. It basically allows for adjusting the wind flow. I don't think that it would save an otherwise bad screen. But the possibility to fine adjust the wind flow is a definite plus.
There are different sizes and bends available to fit a variety of screens. A help to chose the correct version is here:
click. This information proved to be useful. The brackets fit perfect to the N.N. without bending the screen or any other tricks.
From my
previous experiments on the V-Strom with the MRA Vario Touring screen I knew the MRA spoiler makes the screen virtually a few cm higher than it really is. I decided taking the plunge by cutting the screen shorter by 5.5 cm. I used the powerful Dremel tool with a fresh cutting disk. This work is still no cakewalk, mostly because of the massive material. The resulting cut looked rough, it needs to be sanded in several steps, using finder sanding paper each time.
The cutting took away a lot of the scary barn door feeling. Now the screen is 44. 4 cm tall, that's about 10 cm taller than stock.
