Just picked up a '79 z50. Problem is it has a 72cc stamping on the engine. Is this a Honda engine or something else?

Left side head markings are E2_2_L 72cc
Right side head markings are HM-G4

Any help would be great, like to know what I have before going further!

Get the number off the plate by the shifter shaft and look it up on this chart. Maybe a CT 70 motor.

Caked on oil hides stuff pretty well. Plate says AB02E-5005923, that makes it the correct bottom end for the frame, any way to determine if the upper end is Honda or not based on the other numbers I posted?

I would say the upper end is Honda.
