    fast uneven idol

    just managed to get my gs550 started with good old easy start,the idol screw is all the way out(not even engaged).but when i start the engine the revs shoot up then down to 3 thou then up to 5 thou and keeps repeating.

    any ideas

    cheers

    A quick rundown on what you've done.

    It is running lean, for some reason. That could be a nice little list unless you have done most of the things.

      Sounds like yet another bike with an air leak; 30 year old O-rings have a habit of doing that. Maintenance is good.

      To measure is to know.
