    GS400 GSX400 Carb settings

    Hello I was able from bikecliffs site I was able to find most of the carb settings for a GS400 and GSX400

    However does anyone know what the Fuel/AIR mix screws are set to on a stock setup? I would think it would be in the 2- 2.5 turn range. Anyone with experience setting up these carbs. Its for an 82 if that makes a difference but i dont think it will as these models were pretty much the same engine setups throught the years.

    Additionaly does anyone have a link to a parts fiche for this bike. I used the one and CMSL and it seems to work just wondering if anyone has any additional resources

    1.5 -3 turns out, test and feel what works best for you. I tweak them for hightest idle after a good run.
