While I'm not an expert, since the '76's used an entirely different carbs than later years, I'm leaning on no. Older bikes used a keyhole carb, and newer (79-83) 750's (so the 650 MIGHT be different) used a CV carb.
To be 100%, you can look up the part number of the carb itself on bikebandit and compare to the other bike.
Turbos, Hondas, 4-bangers, what could go wrong?
