These earlier GSes look so much better than the 83 and later bikes that I used to race. To me the teardrop style tanks are the best looking on any brand. My 83 and later 550E and ES had one glaring deficiency, carburation! Because of the way the frame was designed they essentially had two carbs instead of 4. They were oval shaped and each contained two carbs in a single housing. More power is made on most motors by getting more fuel and air into the motor and more exhaust out. Never got much more out of the motor but they were fine handling bike that had very good brakes. I still have a bunch of parts and a couple parts bikes that I would be glad to part with.
