    needle valves. Now just need time.

    I've not been into a GS250 carb, but the seats are replaceable on the larger bikes. I had a set of GS1100 carbs off & opened up 4 or 5 times trying to get the leak fixed. Finally discovered the "O" ring on the seat was the culprit.

    Forgot how easy it is to get gsx 250
    carbs out.
    Quicker than having shave.

    town for some tinnies and then I'll
    strip the needle valves out and replace
    it all while having a garden party sat in a chair.

    pulled the carbs.
    removed floats , needle valve and of course
    the tube thing that seats the needle valve
    as per pic.
    I used to be able to do this with my eyes shut
    and forgot about the removable seat ..
    .

    anyway new seats don't fit and needle valves
    too small. this from ebay years ago.

    so old seats and valves back in for now
    and I'll order from dealer. but will
    risk new tap only.

    update :
    Only place I can find needle valve and
    bowl (seat) is cmsl 38 each for
    valve and seat per carb.

    I hope a clean up will do and new
    tap. Mad the price if carb bits!
