And to get those edges nice and factory smooth....
Ooolahlah!
And installed nice and as good as it gets. Now you just simply bolt the slider in place. It is idea to have the hole just a tad larger than the stem so that the slider and spin without much rubbing. If the hole it too tight it just will cause the fairing side panel to bind against the pieces around it from the vibration from the slider. You know... an AK-47 is loose and just works better than other comparable guns. I believe in the same principals here.
