Didn't change 'em until I was here in NY, but it did make it feel better, and less apt to tilt during wheelies. I have a very easy-to-make bushing tool for XR600R/XR650L swingarms. Well, they're actually caged needle bearings. It takes one on each side, a trivial amount of lathe-work, I think, and you could fit 2 on each side. DDave

I'm OK with adding mass, as long as I don't add weight. DDave

Like Clint Eastwood > said in several of his movies " A man's got to know his limitations". Speaking of rocks, edges, and pucker... http://i122.photobucket.com/albums/o273/EstebanVerde/Ghost%20riders/StormMountainDonner025.jpg This is what happens when the bottom of a 650L fork tube catches the edge of a sharp, elongated rock, levers it out of the ground, and lifts the front wheel & drops it sideways. Another inch to the left would have been Big Air. -Jeff-
