I have a 1980 CB750k that I just purchased the other day. I am trying to find out some of the original info. on the bike. Did they offer any factory upgrades back then. Dumb question I know but i cannot find out much info on the web. From what I found out on the web in 1980 they only made the bike with 85 mph speedo. Mine speedo goes to 140. My bike is white and black but from what I see they only made it in red  or black. I originally thought mine was a repaint but under the tank is white, the side guards are white on both sides. I have wire wheels instead of mags. Any help out there. It may indeed just have been a customized 750 but all this stuff looks factory. Thanks,
