So the other day I was holding the spring to the side stand in my hand. I was talking to another guy at the shop about the best way to put it on the bike when he motions me over. There, in a white plastic cup, were the four carb caps I'd been looking for since I began this project at the end of May. The guy who rebuilt the carbs I guess had put 'em there for some reason and when he quit - leaving the bike literally in pieces - nobody knew where they were. In my excitement I can only gather that I put the spring down to look at the caps. Now I've spent about half an hour looking for that *%)$ thing and can't find it anywhere.
So, anybody got one? '71 CB500. I think it's the same spring as on 350's & 400's - p/n 95014-72402 . At this point I'll just buy a new one rather than spend any more time looking for it.
On the plus side though, I don't have to buy a whole carb rack just to scavange the caps
