This is one of those clever mods that is simply too good not to do. I used the p/n 58022-07A kit for '01-'08 bikes, Mid Frame Air Deflectors. Unfortunately, as clever and effective as the mod is, it was also the biggest PITA I've ever experienced over the past 6 years and many, many far more involved mods I've done; this kit simply was not designed for folks with above-average hand size. It was made a bit more difficult because I retained the chrome mid-frame covers which adds a bit of thickness/distance between the deflectors and the various threaded inserts used to attach the deflectors to the bike which was partially dealt with by using longer bolts. Perhaps the '09 and newer bikes with the newer frame will have an easier time with the installation.
That said, it was still very worthwhile and thanks, again, to Doc for posting it.
