no worries, not throwing nothing away yet.
i still have a lot to learn about the old boxers, and while i know a lot of people with from ADVrider.com they're mostly into the newer GS bikes, KL\TMs and stuff like that... so i've got a lot to learn, but i'm a quick study, and in a year or so, i'll be well equipped to answer these types of questions like i do for the KLRs at KLR650.net. i can't tell you how often we answer questions about the brakes, suspension, the carb, subframe bolts and the infamous "doohickey".
i haven't seen any markings on the rack yet, but how would i tell if its a Renyolds or not?
