      Well, it is a bit rough. My bike is exactly like it except two model years older.
      The engine is rock solid, many claim the 1977 GS750 engine is based on that engine.
      The pluses: It has the full fairing, very rare.
      The seat appears to be in good condition.
      All the body work appears to be there.
      The windshield appears to be in good shape.

      The neutrals:
      It has a header, some like that, some prefer the stock exhaust.
      No pics of the right side of the bike. Why not?

      The negatives:
      Paint, as observed, is really rough.
      The bike originally came with matching red wheels, which tended to turn orange over time. The front appears to be repainted, but not the back.

      Observations: If it is indeed the starter, it is an easy fix. Remove the carb bank, remove the battery cable, and the two bolts holding it to the engine cases, and it slides right out. I rebuilt mine last year with a minimum of effort, all things considered.
      It has Mikuni BS34SS carbs, with all the usual "rebuild them or else" connotations of the GS Mikunis.
      The decal set repros can still be purchased for $200 American.
      I like mine; it is lighter than the GS and a lot more flickable.

        Sure it can, send the bodywork off to Larry, while it's gone fix everything else.

        I have restored far worse, except for sending the bodywork to Larry.

            Nevr2old or something like that. He does exceptional paint jobs.

Do it all at one time, even if it's just to lay down a couple of coats of clear to protect the base coat. Then you can sand it smooth before applying the final clear coats.

                That is not really an option anymore.Larry moved and can't do paint anymore sadly.

                  Yes it can be fixed with enough time and money , besides what has been stated, if you are true'ly interested bring a good fully charged battery when you go to look at it , and try to start it , because if it is true'ly the starter it is a easy fix , if it is the starter clutch not so easy. I believe you have to split the cases on a Kawaski to replace the starter clutch.

                    Money pit. If you're building it to ride, go right ahead, but you'll be over your head on it very quickly. Be different it was the Turbo model.

                      FYI
                      the 77 GS750 engine was based on the 1973 Z1 900 kawi engine.
                      suzuki then grew it to 1000CC in 78 and added the quieter helical primary gears and removed the kick starter.

                        I have also read that the 900 was based on the 750, which Kawasaki chose not to deliver when Honda beat them to the punch with their 750 SOHC bike.

                            my experience with the 650's is that they are an insert bearing design.
                            and doesn't the 650 use a chain to drive the transmission rather than primary gears?
                            i was also under the assumption the 750 kawi was closely related to the 650's as far as internal design..
                            with this information the above design seems really different from the Z1 and the GS750.
                            anyways....that's how i came to my conclusion.
                            to my knowledge suzuki got away from the straight cut gears because of the noise/whine.
