The 82 750 CSR is the KZ750-M1 CSR Twin (and not the same as the 750-4 models). I'm pretty sure the Twins had pretty much the same engine throughout the entire model run. The earlier models had points ignition & maybe a different charging system (not sure) --- some 440s share some of that stuff with the 82-84 750 twins. A good amount of other stuff is different from the earlier models. different frames, wheels, tanks, fenders, seats, meters. You can compare stuff at partzilla or maybe Kawasaki.com depending upon what the Kaw site has listed.
