We all love photos and projects - thanks for posting the link.
The coopermine photo gallery thing on this site can sometimes be problematic- at least I have found so when using my preferred browser (Mozilla Firefox), but it m ore or less works OK once one figures it out.
I had a somewhat similar story with my LS, though it hand't been sitting outside, it had been sitting in storage (an apparently damp storage, too) for at least 10 years of its life before I bought it in 2002. I've replaced pretty much all the same items that you have done, but haven't had to do the valves/seats yet - amazingly they looked very good, but the bike had only accumulated 14K miles up to that point when I bought it. At least no one had put an ashtray or cupholder on it!
