This was my exact bike right here. 1980 FXE Super Glide. Looks like a sporty but isn't. I've still got the two-into-one exhaust hangin' in my garage. If you don't know Harleys, the final drive (chain or belt) should be on the left for big twins, right side for sporties.
BTW by, big twin doesn't mean just a bigger engine (1200) it's still a sportster. I'm sure lots of people like em, but I didn't. Just my opinion FWIW
