Yes, sort of. The problem is the springs are too weak. Even without the shelf the windscreen bounces around when teh bike goes off road. The solution is to add some additional springs "over" the existing springs. With the new springs the windscreen is still adjustable, but MUCH more stable. I don;t even think about it anymore.
I did a write up on it somewhere. I'll go look for it.
Found it, but looks like the pictures disappeared. The link still works though.
