    problems with my 83 GS750es

    I'm new to this bike and this forum. I have a 83 GS750 I turned into a caf? racer. It has 28k miles rebuilt and fully cleaned the carbs, pod filters, Mac 4 into1 exhaust too. Fires right up, idles fantastic and revs good. But as soon as you get on it and try to ride it it bogs out and runs like a turd. Anyone here have the same issue with similar mods if so how do I correct the problem?

    Sounds like you need a Dynojet jet kit. You might want to check the Newbie Mistakes thread linked in my signature for a list of things to watch out for.

      You do that modification?
      Modify the intake and exhaust system, also then requires modification of the carburetor.
      Did you change the carburetor jets?
      WHat they need to be changed to is a big question. I dont have answer. I understand it takes some trial and error, lots of experience and finesses.
