Hi again,
I helped a friend of mine replace a burnt up Dyna ignition with points on a 1973 CB750K, and we robbed a 1976 CB750A model of its advance mechanism, and points plate. I noticed a different number on the CB750A plate, 333 vs. 300 on a CB750K model plate. We used the 'A' model as the cam was still on the advance mechanism, and the parts were all from the same bike. The CB750A is a 1976, and the bike is a 1973 that we installed it into. I static timed the points, and we didn't have time to fire it up last night. We also kept the green Dyna 3 ohm coils. Is there any incompatibility here? Thanks!
Charlie
