Hi all, does anyone know details on the FZ. My compliance plate states 11/81 CB750 FZ. Research suggests that the fz was manufactured until 1980 and the frame number of RC04-23--- and engine number of RC04E-400 might point it towards a 750F2C. After doing some electrical work i believe the wiring diagram of the 1980 CB750F is closer than the 1981 model. I was thinking it could be an 1980 model which took a year or so to get its Australian compliance plate. But the bike has slotted front brake disk which suggests 1981. Any ideas?
