Hi Everyone.
Just for anyone thinking about mounting these Railz or any sliders that require drilling through the fairings a better (and quicker) way to "line things up" would be to use a laser level. Place the laser on a table at the height of the bolt that will mount the slider, then line up the laser with the center of the bolt. Then without moving the bike or the laser, replace the fairing on the bike. The laser will point the the exact spot that needs to be drilled. I think this is more accurate than the method mentioned here as the sharpened bolt will bend the fairing before the fairing can seat all the way and not mark the true location of the hole that needs to be drilled ( although it should be close enough).
Hope this helps.
