Stu here from Portland. I had a '70 CB750 and a '72 CB500 that I bought new (raced the CB500 to 2nd Place in OMRRA 500 Prod class back in '73) Now you know I'm an old fart! Currently I have a restored '70 K0 750 as well as as a restored '72 CB500. I also have a '73 basket case CB500 that I have plans to make into a cafe style racer. Looks like lots of good info here and I will be using it when I start on the project this summer. First I've got to get my '74 Ducati project finished....
