    Help with a basic carb question

    Hey guys, easy question and I've been hunting around for pictures in the manuals I have and online... there are blowout pictures but they don't seem to answer my question.

    I'm looking at the carbs I had rebuilt for my 1979 GS1000N and going to reinstall them shortly. So far clear that the four tubes running from the bottom are for overflow and should be grouped together to the side of the engine.

    Unclear on the rest. There appear to be 3 carbs that have an inlet(outlet?) midway up, not on the forth, anyone solve this mystery? And there seems to be one large inlet between all 4 carbs (fuel inlet?).

    Anyway, can anyone help with a good diagram or video or just tell me how to specifically route the remaining tubes?

    Thanks a bunch.

    If you have a stock box, the right one goes over the top of the box and just behind the frame..then straight down between the engine and the swingarm.

    The left one goes over the box the same way, then down between the engine and swing arm. You trim them off maybe an inch below the oil pan.

    If not stock box, just run them down between the respective carbs and between the swing arm an engine.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      AND only the ones on 2 and 4 are the vents that get run down...the one on 3 goes to the vacuum port on the petcock. If you do not have a stock or otherwise vacuum operated petcock..cap 3 off or youll have a massive vacuum leak.

        Fantastic. Am I missing the diagram in the manual that shows this or am I just supposed to smell that number 3 goes to the petcock?

        So the big port in between 2 and 3 is fuel intake from the petcock yes? Anything else I should know about putting these in?

          Put a length of hose on it and put the other end inear your ear and hit the starter button...you will hear l it pulse as its sucking air.

            Yes...the big one in the center is the fuel tee that feeds gas to the carbs.

            If you havent broke them down and completely rebuilt them I suggest you do so. Is this the bike that has sat dormant for 10 years from another thread???

            If so, you need to redo them...

              Hey, yes I've had them completely rebuilt ground up. New tires and tubes, top end rebuilt.

              Stoked.
