So I’m enjoying my new bike tremendously but have a slight issue. I have a 2010 C50T. Everything’s good till about 70kmh then my head gets shaken around like crazy from the buffeting. From what I can tell the windshield is set as high as it can go. I’m enjoying the less wind on my torso but the head wagging I could do without. This is my first bike with a windscreen with not sure if it’s normal or where to go from here. Thanks.
