There is a dedicated GS site that I'll introduce you to later. The GS series was the first Japanese bike of the era that handled well. Heavy by today's standards, but can be made into an everyday rider fairly easily. The electrics sucked but there is a Series R/R conversion that pretty much cures that and allows for LED conversions without frying the stator. I'm running a Custom sports touring '78 GS1000E, 4-1 Vance and Hines pipes, Pods and stage-3 jet kit getting 44MPG on regular pump gas. It would have been the hot rod back in the day but will run with the 600 and 750's today without having to paddle through the gears to make power. The weight is still a disadvantage but makes for a solid comfortable riding platform. It's hard to beat an air cooled roller bearing motor.
