Frame - cb7502009970
Engine - cb750E-2017718
these are the numbers off the bike. I submitted to a website and they came back with 1972. Ok I’m very literal so I now get what your saying. Thanks man.
Just bought a 1971 or 1972 cb750. Engine serial and frame serial come up as 1972 but was registered as a 1971. So if I wanted to purchase a whole new wiring harness would it make a difference ? Comments and opinions welcome. Thanks in advance
