I have owned my Vee for over a year. At moderate speeds I have always heard an unpleasant roaring noise that seems to be produced from a location lower than the windscreen. It sounds kind of like the sucking noise of a vacuum cleaner crevice tool. I cease to hear it at speeds exceeding roughly 50mph, possibly merely masked by the increasing wind turbulence about my helmet. Has anyone else experienced this, or know of a remedy?
