Well.. put the kids to bed, indeed it took longer to unmount my ammo cans than it did to install the rack. Probably a 3-4 minute install total. Much like everyone else's observations, it needed a little tweak to fit. I actually thing this is by design, as it adds significant rigidity to the rack and rear of the bike.
After install, I also agree with a post that I read a while ago about replacing the tiny M6x1.0 bolts under the seat with stronger ones.. I might even consider drilling those holes out and running a nut on the bottom with a lock washer.
I'll echo my previous post again.. Top Notch. Money well spent.
