Thanks mate, the visor comes with the three screws and mounting grommets. All you need is an 8mm drill and a little care, easiest way is to hold the visor in the correct place and spot drill the front centre hole. Remove the visor, drill the screen and mount the visor using the screw and grommet provided, that way you can get it straight to enable you to drill the other two holes. Just to make sure that you keep the drill straight, put the grommets behind the visor when you spot the other holes. As regards vibration, it does a little bit, but not much , after a while you dont even notice it and anyway, who looks through the screen when they're riding?
Hope this helps
