    2001 XL800 problems

    Rebuilt the carbs on a 2001 XL800. Set the low/high per factory, closed the throttle plates so I could reset the idle. unit fires fine but idle runs away on hose. Will rev above 4500 all by, pull choke then it will rev again above 4500. Checked to make sure throttle plates closed, still revs above 4500. disconnected power valves, still does same thing. New gaskets at base of carbs and manifold. Any ideas?

    Thanks

    sounds like you have a fuel dribble or a vacuum leak

    Where do you think a vac leak could be coming from? Are the power valve motors known for intake leaks?

    Air leak would have to be where the carbs attach or around the plate that seals the reeds.

    Powervalves wont cause this problem

    I think he meant PV motors in general,meaning style of motor not the actuator

    I had a 701 do that when one seat was stuck closed with bad fuel residue.

    Has anyone ever used any type of sealant around the reed valve oring gasket style seals to help them seal better to the manifold plate?
