hi guy's, im new to all this just registerd with your site. well to the point. i too have the problem with buffeting with the triumph summer screen,on the ride home from the dealers i had the feeling of wasteing my hard earned folding stuff,i have made some extension brackets that tilt the screen ,when you look at it from the side its almost upright,common sense should have told triumph designers that its not an ideal angle for air flow?.im no rocket scientist but i came to this conclusion when washing the bike and rinseing it off with a hose pipe,spraying the water directly at the screen you can see how its dispersed, much like how the air would be acting when on the move. i'm 5`10" and with the adjustment(trial and error)im just about happy with itnow i can cruise all day at 85mph(uk)aprox 130kph?.if its a bit windy i put my feet on the back pegs this is more of a sports bike position but it seems to lower my head height just enough and also makes you sit with a straighter back,as rideing long distances seem to make me slouch and end up with a bad back. well ive boared you all to sleep now. hope this was some help.
