    Idle Screw non responsive

    I own a 1981 GS450. Have just removed the entire engine to have one of the cam chain tensioner threads re-threaded.
    The engine has now been fitted back into the bike and it runs again -YEAH!

    The idle screw is non-responsive though.
    I used to use it when cold-starting in place of the choke (Which hasn't worked since I bought the bike).

    When I turn the choke in the 'on' direction it cuts the engine. The engine would run perfectly when the choke is in the 'off' position.


    Now that the idle screw doesn't respond at all I have no way to keep the bike on idle except by holding the accelerator slightly.

    Any help?

    Take the carbs apart, clean them thoroughly and fix all that stuff.
    It's all simple, just takes a little time.

            sorry to thread jack but how hard is it to take apart, clean, and reassemble the carb? I need to do but I've never worked on a bike before. I'm very interested in getting my hands dirty because I would like to really clean up and repair my bike.


            Especially after visiting this forum. There are so many beautiful GS's on here.

              It's not hard at all. Look on the main page for GSR, there is a "Garage" section. In the Garage, you will find two guides for cleaning your carbs. One is for the older VM carbs, the other is for the newer BS (CV) carbs. We have no idea what you will be working on, or where, so may I suggest that you fill out some information in your profile? Knowing what you are working on really helps. If you also put in a general location, you may find that there is someone close enough to get their hands dirty along with you.
