    77 gs 550 overflow tubes are flowing

    New here, and stumped. My son and I bought a gg550. Bike runs awesome, but 3 out of 4 carbs squirt out fuel in an odd pattern. It's like they take turns. About every 5 seconds one squirts, ten stops, then the next one does it. Is this normal, possibly having dirt in the system. The bike runs so well, would hate to have carbs completely rebuilt do 450 dollars if it's something that could be easily fixed. Thank you!

    The carbs need to be cleaned but no reason to spend $450 to do so. Look in the Parts and Services forum and look up Chef or Steve. They will fix up your carbs for a good price. If they won't PM me and I'll do them for you. Or better yet rebuild them yourself. Find the VM carb rebuild tutorial here and get busy...http://members.dslextreme.com/users/bikecliff/ And whatever you do don't waste money on "carb kits" other than some new O-rings and float bowl gaskets. You may need float needles but cross that bridge when you get to it.

    BTW, check the Newbie Mistakes thread linked in my signature so you know what to look out for. And do all the bikes maintenance: valve adjust, new brake lines, etc.

    Good luck

    To measure is to know.

        Yup, sounds like the floats are sticking.

        I can just echo what Ed said.

        Cleaning the VM's is no biggie, given you work with some care, in an orderly fashion and are able to follow the instructions given in the linked tutorials.

        I successfully did so just recently (multiple times, but that's another story), and I'm a complete noob to those things.

          +1 for doing it yourself. I had to disassemble and clean twice as well but I actually learned a lot. Seems way harder than it is. The guide Ed linked to is great!

              Make sure you order new O-rings from cycleorings.com/VMkit.html

              1980 GS1000GT (Daily rider with a 1983 1100G engine)
              1998 Honda ST1100 (Daily long distance rider)
              1982 GS850GLZ (Daily rider when the weather is crap)

              Darn, with so many daily riders it's hard to decide which one to jump on next.
