1973 z1 engine numbers? 10 Jul 2006 12:24 #60789

kzmarvo Topic Author Offline User Posts: 344 Thank you received: 0	My friend found a 1973z1 in a scrap yard and there is no numbers on the block except the 903cc. Did they not stamp the early bikes or what? The frame says 73. Watch it folks,i have sticky fingers when it comes to a nice looking set of handle bars:)

IowaKZ Offline User '80 G1 Classic Posts: 290 Thank you received: 5	Look up in the header above where it says KZ Information. Then look under Model History. In there is a bunch of material on the '73 Z1. It says that there were engine numbers. Maybe in a weird location compared to later? Did your friend pick it up? How much? Any Pics? 1980 G1 Classic Bettendorf, Iowa

Jeff.Saunders Offline Vendor Posts: 1290 Thank you received: 181	ALl the engines in bikes had engine numbers starting with Z1E-nnnnn The only cases without numbers are replacement cases (and engines where the engine numbers have been removed by someone).
