I decided to swap in a Bandit 1250 motor into the GS750 frame. I still have the GS1000 motor with a big port intake, but I will rebuild that motor later. For now, my goal is to keep the motorcycle under 400 lbs and tune the engine to churn out 100 lb-ft of torque.
I will be running an in-line fuel pump with a fuel pressure regulator, so I don’t have to mess around with the GS750 gas tank. The Bandit 1250 fuel pump seems to be problematic from what I’ve read in several forums, and expensive too.
