Good work, just keep spraying the exhaust nuts with oil, relentlessly. With a bit of localised heat and a bit of time....... you never know your luck.here's mine and it had been left in the weather for 12 years, i had to do loads of work and just smarten it up a bit as well. 1979 JDM 750FZ daren't touch the exhaust nuts i had enough with everything else breaking so the pipes got covered, they are a mess
My original red CB750 K0 owned 42 years previous owner Honda Power Road (when Honda was based at Power Road London UK, my USA K0 genuine 21,000 miles but I renovated it all over winter. Mechanically in brilliant condition but see last picture how I bought it, who has pooh coloured paint! Engine is an 836cc HiVo crank, CR works carbs, ported F2 head, high list cam waiting for me to finish it off.
Nice bike. Some nice scenery there too.
