Adamjon,
Bear in mind the '81 750 is a DOHC, unless I'm mistaken. Still a very nice ride, but this board is particularly for the SOHC 750. You can still ask questions, hang out and learn, but I'd keep anything that's specific to the DOHC engine or style over at the Slick's Choppers forum. Thanks to Lestat99 (Slick) and Lady Dr., there's a forum thread JUST for DOHCs! Check it out.
