Very nice Z1B! Engine # is Z1E-[hidden information] and Frame # is Z1F-59478 (102 difference). Was restored by the famous Hick's brothers from Bath Michigan. Date stamps are there. Exhaust are original 1975/1976 stamped. Shocks are vintage correct reproductions. Of course all the electricals work and the bike runs great! I have a 1975 and 1976 Honda Goldwing GL1000's for sale.
