I was kicking around the thought of buying another CB that is in ridable condition (or at least closer to it then my K4) to get back into riding as i rebuild my 750. I was thinking one of the smaller CBs may be the ticket be it the CB500 or 550. Does this seem to be a good idea? This is my return to riding so im kinda worried about winding up in a bad situation on the 750 if i rushed its rebuild because i wanted to ride it right away.
