I've been spending my time cleaning and polishing (especially stainless bolts) while I wait for the engine to be done. I love freshly polished aluminum against gloss black - it looks so clean. I find it very satisfying when parts go from chipped, dirty and dull to fresh and bright. I don't polish my metals to mirror shine - I'm too lazy for one thing - but I also like the warm glow created by less polishing.
I mentioned that instead of a turn signal indicator, I'm using that hole in the headlight bucket for my electric start button. I tried to find a button that mimicked the original indicator. Ridiculously, I think the thing I'm most proud of is getting the button to light up when I push it. Originally I wasn't going to bother, but I think it looks really cool!
I placed the last of my big parts orders - I'll probably need odds and ends, but I shouldn't need anything else major. I still need to clean the carbs, but then once the engine is back, it'll be assembly and wiring. Paint won't come 'till the winter though (I think I might rattle can it for right now).
One other odd thing - I bought this project basically as a basket case bitsa bike, so I don't know how much of the 50/2 parts started life together. What I do know is that several of the parts, including the brake linkage, steering damper, and various smaller pieces, were once painted metallic blue. That would have been a bike to see!
