I am embarrassed to ask but, I have been messing around with the 3 little screws that hold the wheel hub fairings (flat plates ) on and can't seem to figure out any good way to keep them in. They seem to vibrate off, or strip out. I tried replacing the screws with some nylon ones, but they fell out also. I know it is a really minor problem but it is bugging me. A friend said just to leave them off. Does anyone have a fix for this? Tim
