    GS550 1980 carburetor

    Just purchased a Suzuki GS550E from 1980. I'm in the middle of restoring that bike. Already replaced damaged wiring and fixed all electrical problem. Now I'm working on carburetors. Looks like some smart guy messed with them real good. I did rebuild three of them but have a problem with the forth one - need to replace entire carb body.
    I need help to figure out on what year and models the carburetors are interchangeable. Someone told me that the GS550 and GS750 have the same carburetors installed. Thanks all for any help or advice.

      That's true, both the 550 and 750 came with BS32SS carbs. The only difference was the jetting, and I believe the rack they mount to. Which body do you need?

          Welcome.

          In another thread Steve pointed out that the spacing between the carbs - particularly the center two - could be problematic w/r/t the throttle linkage from the larger bikes. The 550 and 650 carbs should be identical other than jets. Larger than that and you need to start considering the throttle connectors as well.

          Figure out which carb body you need and put a request in the "parts wanted" section. More than likely someone can help you out.

              Thanks all of you guys for prompt replays. So looks like all GS550, 650 and 750 carburetors are interchangeable.There is a bank of Suzuki carburetors from GS650 on Ebay for $40. Looks like a great deal to get some extra parts for future repair. Thanks again.

                  550 and 650s are the same carbs
                  the 750 and 850 have the same 1&4 carb but there is a wider spacing on 2&3 since the cylinders are larger.
