    Newby '84 1150ef rebuild advice.

    So I inherited a GS with two frozen plugs, all attempts to remove the plug cores failed so off with the heads and carbs.

    After a two hour wrestling match with the carbs it's time to clean and maybe rebuild, the GS hasn't run in nearly 20 yrs and 28K kms/17K miles what are the forum experts suggestions?

    My first observation, these things are not maintenance friendly as far as removal, is there a different filter arrangement than the stock set up that would allow for easier removal in the future?

    Are there carb kits that the forum recommends, and carb kits to avoid?

    Are these carbs someone with only a basic mechanical knowledge can handle or should I hand it over to an expert?

    Too bad about the plugs.

      Thanks that was a great Tutorial Steve, I think I can I cope with that.

      Are there any particular brand of rebuild kits that you'd recommend?

      I searched the web for individual air filters and there a few, will they affect the performance of the GS.

      Do I need to adjust the carb jetting if I go that route?

        No carb kits at all, just O rings

        Why switch to pods? If you do it correctly, this will be the only time you pull the carbs

        Not only will you have to rejet, you'll need a dynojet kit

          Carbs cleaned everything inside was okay, just need rings to arrive for reassembly. The forum resources were invaluable in assisting with that job.

          Got my cylinder head back last week, Frozen plugs removed from cylinder two helicoils put in, and the head rebuilt.

          Cylinders honed and cleaned. I expect my gaskets, piston rings and many more parts to showing up at my door over the next two or three weeks.

            So the carbs are all cleaned and partly assembled and I thought I should record the main jet size I before I put it together and install it on the engine. I found carbs 1 and 4 are 120 and 2 and 3 are 122.5, Is this normal? The carbs had been rebuilt once before 25yrs ago is there any reason someone would've deliberately done this?

              You can download a manual for your bike here and then look up the jet numbers...http://members.dslextreme.com/users/bikecliff/

              It wouldn't surprise me if Suzuki used staggered jets like that.
