The BSA Website is here:

I was able to get my chain back on the bike with a new master link. It's nice to work in the garage, that way I can give everything a good cleaning, especially in hard to reach areas that aren't too accessible with the chain on.
And I just got back from the Steel City MX Races, so there's another MZ Baghira trip documented here @ tigerboy.com
