Wow. I stumbled into this thread looking for information about the non-running, leaking everywhere, basket case '81 R100RT I picked up last week. I've read every word. Thanks for posting the wealth of information on stuff I had never considered. My learning curve will begin once I dig into it later this summer (too much riding to do in the meantime). Perhaps I'll catch a few of the folks here at the MOA rally later this week - I'll be on my Oilhead. Thanks Ray!
