So... just picked up a 1981 CB750C, and I've noticed the parts market isn't exactly as big as the earlier SOHC market is.  I was wondering, is there too much difference between the two?  I'm especially concerned about the frame and forks, because I'm thinking of possibly getting a new frame for this one.
