Part of why we do forums and stuff like this, he mentions at 5:10. It's about learning things, gathering knowledge and techniques, and passing them along to the next guy. Sure, it's 30+ year old technology, but the engineering in the CB750 is just amazing. Most of it done with slide rules, drafting tables, hand tools, and constantly revisiting the product to make it simple, reliable, and powerful.
In my job, I deal with customers and clients. One of the biggest kicks I get is empowering my customer. Doing this gives them a sense of ownership and helps them be self-sufficient. It helps me as a teacher and guide, to learn how to impart the things I've learned to others. Also, it keeps them from calling me at all hours of the night, asking me how to change this or implement that. So it's a bit self-serving in a way.
Great video. He's a craftsman. I would expect there's nothing he couldn't make for you, or improve on what design you have in your head or on your bike. And yes, I like his mom in the shop. Why not? It probably keeps _her_ young as well.
