Pat Walsh crashbars/bash-plate installation notes
I got these installed yesterday on my DL650.
My only advice to a non-mechanic (like me) who is considering doing this is that getting the side-stand bolt loose was a bear. When they put that bolt in, it wasn't with the idea that you would be removing it. And it didn't make me feel any more comfortable having the bike up on a track stand while doing it. (This is not to discourage you, but to prepare you to be patient and careful.)
I chose Pat Walsh over, say, SW-Motech for a couple of reasons. The foremost was design. I'm not a mechanical engineer, but I do know that the shortest path between two points is a straight line. Fewer tubes mean less weight (I'm assuming it weighs less, but I don't honestly know). The heart of the setup is the rock-solid, straight crossbar.
Now, about that crossbar: the instructions said to use the top holes on the bracket. Every photo I've seen has them installed on the bottom holes. I noticed crossbar wouldn't quite fit flush on the bottom holes, anyway, but I'm still curious: what gives?
