What year is this engine?????

Hello. Thinking about buying an engine. I need to know the year of it. The serial number is GS750-61551

Don't know if this wil help you but my 77 750 was manufactured Sept 76 and has engine number 17168 and my 78 750 was manufactured May 78 and has engine number 72445. My guess would be that it's from a 78 model year bike.

The engine number you have quoted comes from a 1978 GS750C model.

Thank you for the replies. Next question, are the 1977 and 1978 models interchangeable? I have a 77 model that has bad rings, wondering if I could just swap in a 78 engine? Thanks.

Yes. Not a problem.
