There should be a VIN tag attached to the steering neck, right side (as seated) that will list VIN #, month/year of manufacture, and of course, Honda as the manufacture.
On top of the engine cases (below the carbs) will be an engraved serial for the engine. These 2 sets of numbers will NOT match, never did. You can sift through the Manuals section for a reasonably close identification on the year for your motor, but the VIN tag will be empirical for your frame. If the tag is missing, the VIN is etched into the neck on the left, and it too can be researched the same way.
