    Can I use GSXR 750 carbs in a GS750?

    I just got a sweet deal on a 1980 GS750. Now I'm thinking about putting some money into a little performance upgrade. A friend of mine wondered if we could use the carburetors from a GSX-R750 in there.

    I know I saw a lot of good information in this thread:
    Place your GS performance, tuning or mods related questions in this forum.

    but they mentioned carburetors for the Gixxer 1000 going onto a GS1100, and I want to know if the 750 fits.

    I appreciate the help that you guys have given so far.

    I've never done it but I understand that the air/oil cooled GSXR carbs will line up with the intake ports on the GS750 but not the water cooled GSXR carbs. Again, I'm not an expert on this by any means.

      I've read that balancing the carbs is a headache, and I only want to do it once. This bike's been sitting a while and needs to be thoroughly re-built, so I'm wondering if it would be worth it or just get some nicer carbs to begin with.

        addendum:

        I meant that everything but the engine and frame needs to be re-built.

          Get the 88 & newer AIR cooled GSXR carbs from a 750 or 1100. The 750 & 1100 Katanas work too. Ray.

            Wonderful. I'll look for a set of carbs off of a GSX-R 750 between 88 and 92. The GS750's also got a Supertrapp 4-into-1 exhaust.

              Watch out for the 91/92 NON Calif. carbs! They are 38mm & won't easily fit the GS manifolds! The Calif. models are 36mm & will fit. Ray.
