can anyone make a suggestion as to why the mirrors on my foxeye fazer move at will!!!
I have removed them but have no idea if any parts are missing.
They constantly move rearwards.
I had a similar problem with the right hand mirror on my 2010 FZ1-N. If I went particularly fast the mirror head moved so that the mirror became useless (it was definitely moving at the mirror head joint, not further down). I raised it at 600 service and they tightened everything that they could, but it got slowly worse. I've just had the whole mirror replaced under warranty - my dealers were quite amenable to putting a claim through. It is fixed now, though I've noticed that they've set the mirror stem at such an angle as to "discourage" it from moving anyway. I wonder if that means that it's not the first time that they've seen this particular problem.
Actualy I've just realised that, I think, yours is an older bike and will be out of warranty. However, depending on where it's moving, it should be possible to set the stem angle so that the mirror can't move in the direction it's tending to (assuming that it's the mirror head, like on my bike, with a ball and socket type joint). Just set the stem a bit further forward than you normally would so that the ball and socket is right against the end of its range of adjustment.
