    carb swap feasable?

    I own a 79 gs 850 G, the carbs are pretty poor. Can a upgrade to CV carbs be performed?

    I don't think the heads changed any from '79 to '80, but the throats on the carbs are bigger, so you would need new intake boots and new airbox tubes, too, unless you change to pods. If you change to pods, be prepared for the "fun" of re-jetting to match.


    Just a guess. 8-[

      If you want to use CV carbs on your 850 You would have to replace the Head with one from a 1980/ newer. 79 Was the only year 850 with slide carbs. Also the air box boots

        Are the heads actually different, or just the intake boots?

        I just took a few minutes and looked up all the part numbers for the cylinder head assemblies on Bike Bandit. For the entire run of '79-'83, there is a different number every year except '80/'81. What changed?
