what year is our CA77?

[azcycles]

Frame number CA78-1007977
Engine number CA77E-1008035


We think it is a 1967 but just wanted to get others opinions.

BTW I thought I would enter it in the registry and see if i can figure it out that way, but the form won't accept any email entered and keeps resetting saying the question is mandatory. No matter how many times i have tried to enter the email
Thanks,

Look for the white tag on the wiring harness. Under the tank or in the mid section of the frame. It records the date of manufacture of the harness.

'67 would be a number starting 105...

Unfortunately there is no paper left. How come the published numbers only go to 64? Has anyone compiled the numbers from the registry?

Honda changed to a 7 digit sequence in 1964 probably because it became obvious that some bikes had sat in a dealer's beyond their model year.

The later system just ran on from 1964 with no specific breaks for the year. e3Steve compiled this list from members' inputs. It gives approximate years for CB77 but the other bikes should follow a similar path.
