Good score on the mirrors.. I have been using them for 6 years now on my z1000 and 4 years on my 10. You really have to watch it when you install them... they do break at the red circles. I watched a friend snap them off trying to get the mirror pivot tight enough so the mirror wouldn't move. Also it is good practice to take the mirror off and put a bead of black silicone/RTV behind the mirror. The mirror will vibrate loose and make some horrible racket when it shakes loose. It won't fall out but you will be able to slide the mirror around in the housing in a few days or weeks if you don't do the RTV thing. Brings up another point.. be sure you have the correct allen wrench to take the screw off, it rounds off pretty easy.
