New to HD and have had head shake issue since day one..anything over 35mph. Started with a LRS recurve and helped some but while doing some reading, I tried removing my helmet visor...shake amount way down. I could feel all sorts of fast air around the top of the tank. Lower area wind was suspected cause. Just added the side fork deflectors and the center fork air baffle and problem solved! Being new to the game I figured it was all part of the fun....until we took a long ride and I was miserable after an hour. Now I can see clear and Im really looking forward to hitting the road. Could not have figured it out without all the knowledge here from past and present years...Thanks!
