#N:umn-cs:4000001:000:529 umn-cs!mincher Aug 18 19:22:00 1984 I have a Yamaha 650 Maxim which has had a tendency to shimmy if I let go of the handlebars ever since I put the Fairing on it. Recently it has been getting worse, to the point where I have to hold on to the grips firmly to keep it from jiggling, and the bike feels sqirmy going into tight corners. Does anyone know what causes this? I think that the jiggling is at the same frequency as the wheel revolution, but I'm not positive. Please send responces to: ihnp4!umn-cs!mincher Thanks, Paul Thompson

There are several reasons why this can happen... shocks, lack of a steering dampner, loose wheel spokes, etc. but a couple you might seriously consider are: * The fairing is probably a handlebar mount and therefore adds 25 or so pounds to the heaviness of your steering and then the shape of the fairing causes the wind to push it one way. Once it reacts to that push the shape of the fairing has changed in relation to the wind and therefore pushes it the other way. This sets up an occellation back and forth causing the wiggle. * This one actually happened to me on a race bike. The front tire was out of balance. Not in the normal sense that you think of balance where one END of the circle is heavier than the other but that one SIDE was heavy then rotating around 180 degrees the other SIDE was heavy! (hard to explain) What it did was cause violent shaking, not bounce of the front wheel. Talk about wierd. Anyway, hope these and other inputs help. Bill Landsborough
