I started as a budget build. Like you, I had a precise plan starting out. I was online looking for info on rebuilding Keihin carburetors and stumbled upon Murray's Carburetors and thought they were so cool that I figured, ok I'll just upgrade my plan to include these. Then when looking for wiring info, I discovered Motogadget stuff and at that point I lost my mind. No longer a sensible semi budget build, now it's a I need the best of everything build. I've always loved well designed tools, parts and machinery. I don't have the welding and fab skills that a some of the builders here do. I did find a good welder fabricator which was a Godsend because I got that work done exactly as I wanted. So my next best thing is to pick out a theme and nice parts. So, I've done that and it looks like if I continue to do the grunt work correctly and put it all together well, I might end up with a nice build that won't embarrass me next to the truly talented builders. I watch builds like yours very closely and have picked up great ideas and advice. It's really big fun. What else do you do when you're 68 years old?
Looking forward to seeing you're end product. Besides good work, you have an eye for what looks good.
