Us minions would consider ourselves privileged to have an early CB750, but you have 3. Not just 3, but each one is absolutely magnificent. Bravo, Sir.

Thank you Liam. I have had some other CB750s over the years, but the K1 model is my favorite. I had a used sandcast many years ago and didn't really know what I had at the time. In 1976, I took that bike on a 5000 mile trip and it ran perfectly the whole way. When I got rid of it in 1977, it had about 60,000 miles on it and I got $1000.00 for it. I had a new 1972 K2 when I was in high school and I paid $1650.00 for it. I had a bad accident on that one. In 1978, I bought a new 1978 model and it was really nice. I have had some others along the way, but these three K1s are my favorites and will be probably be my last ones.
You would not believe the condition that the copper color bike was in when I bought it. It was up in the high mountains of Colorado and had been sitting out in the weather for many years. Most people would have taken it to the junk yard but I saw some potential in it. It was very difficult to disassemble because some of the the bolts had basically fused with the aluminum. It gave me a great sense of accomplishment to bring it back to life. The red one was in much better shape but it had been sitting for almost 40 years.

"I just used the standard silver engine paint that many of us use on the GL1000 engines."
What kind is it, and where do you get it? High Heat Silver, like at an auto parts store?

Very nice restoration and attention to detail, which takes it to the top level of a restoration. The use of new parts and especially the fasteners and paint and polish really shows well in your work.
I believe you also swapped the internals on the engine too, so not just a spit and polish job, but the complete deal.
Cheers

Thank you. The inside of the engine was in pretty good shape so I only replaced one bent shifting fork, the primary chains, the cam chain, pistons, rings, cam tensioners, and a few other little things that I can't remember. I also had a valve job done by a machine shop in Denver. I took everything apart, including the wheels, and installed new spokes, bearings, seals, etc. When I had the speedometer apart, I decided to reset it to 00000 because I figured it was now "closer" to 0 than it was the original 20,400 miles that it actually has on it

. On this bike, I am most proud of the paint, because I am not a professional painter. I have probably painted a dozen or more bikes over the past 10 years and have improved each time, but I am still not an expert by any means.
