Number on 1977 750K7 frame
« on: January 14, 2020, 03:31:22 PM »
My bike has the pictured number stamped in the frame cross piece just aft of the battery box. Does anyone know the significance if any, of this number?

Mine has 2216 stamped in the same spot. Probably used to track sub-assemblies prior to welding. Definitely not a freelancer with stamps.

Or maybe St John's Honda on Portland OR. Surely some detail oriented specialist/enthusiast in re the Honda SOHC 750 knows what the number on the frame means.

It is a job sequence number.
77 vin started CB750-2700009, if owners report relation to vin we can determine if the sequence ran through all of 77 or restarted at some interval like each month.
