If you haven't read through this entire thread, you owe it to yourself to do so. It starts with an abandoned ATK on a dock in the bay, and ends up with a beast that a 5 foot 5 inch woman can ride comfortably. Engine work, frame mods, foot peg relocation, seat height adjustment... this has it all. I wish I had this amount of awesome to post on this blog, but I'll just have to settle for linking to it.
This is another good one by GCRAD1 over on ADVRider about his adventures in working on his 605. Pretty cool pictures of petcock refurbishing, carb maint, bearing repacking, and also him meeting Ron Woods, and visiting De Wayne Johnson's suspension lab, and American Dirtbike.
