I have a 2011 Speedmaster with the quick disconnect summer screen. Still get some buffeting at 70 + MPH. I've heard the lower wind deflectors will eliminate some/most of this problem. Is there any deflectors that will fit on the quick disconnect supports? Or can any be mounted on the fork behind them? So far, I have not found any which appear to be adaptable to the 2011 which has the different fork/windshield design. Anyone out there done this on the 2011?
