Greetings to all, I am new to the forum. I own a 2001 Honda Aero 1100 with about 20k miles on it now - love the bike. I have been experiencing a mild to moderate head shake when riding the bike on curving mountain roads - typically downhill and in curves. A 17 inch windshield and lowers are installed on the bike, and I seem to remember this being less of a problem before the lowers were installed (I bought the bike with a Memphis Fats windshield), but I am not sure about that. I really appreciate how they keep the wind buffeting to a minimum, so I would not want to remove them. No problems when traveling in a straight line, and at highway speeds. At 20k miles, should I consider replacing the steering head bearings, a damper of some sort, etc.?
