I'm going to look at a '71 BSA Thunderbolt tomorrow night and wanted to make certain things like manuals and whitworth tools/taps/dies are still readily available. Had a '70 Lightning from '71 to '73 and still have kind of a soft spot for BSAs and figure an oil-in-frame Thunderbolt might be the cheapest way to get back into the 650s. The story told to me is it's a one owner, complete, stored in his house for the last however many years non running example with 16K miles on it. Apparently the guy is a doomsday prepper and the bike no longer fung shues with his armegeddon. Or something. We'll see. Smart money says it's a half there rust bucket, but a guy's gotta look, ya know? Thanks in advance.
