Recently installed a standard Suzuki wind screen with factory lowers to my 05 C90. City street riding is fine but highway speeds in excess of 55mph are accompanied by vision blurring buffeting and nagging headaches. Have attempted to change out windshield with aftermarket brand, change helmets, and added laminar lip without significant improvement. Have considered purchasing an aftermarket wind faring (Hoppe) but dont want to make such a costly investment if problem can be solved for less expense. Any suggestions for a cure?
