Which numbers don't match? If you are referring to the frame vs. the engine numbers, they never do.

I know the engine & frame don't match. I guess I would like to know the last KO numbers??? At what time frame did it become a 71??? azporkey many thanks to all.

According to the chart CB750-1044650 frame number was the beginning of K-1 on 09/21/70. I double checked those numbers with the Mark Haycock book "Honda CB750" and they are the same!

Put up your frame serial number. X out the last 2 digits if your not comfortable doing so. I have a 5-70 in the garage with frame # CB750-1036XXX

According to here:  http://www.motorera.com/honda/h0750/four.htm

the K0's began with CB750-1000001

the K1's began with CB750-1044650.

No mention made of a calendar date.  I think you might be getting off track on the build date and the "release date" that gets kicked around.  I guess I'd go with the frame serial number as to whether it's a K0 or not.
