I've found a pristine f800s with 6k on it to buy. Problem is, even though it has an aftermarket windshield that is 6" higher with a laminar lip on it than stock, at 70 it begins to lift me back off the bars. Let me add that it has the st conversion handlebars mounted. Any ideas about windshields to solve my problem. The bike is gorgeous and handles like a dream. I hate not buy it, but I can't do 500 mile days as it stands.
