    gs 850 pilot jet size

    Took apart my carbs before the startup from a basket case affair and found two different size pilots
    found 3 40s and one large 22.5
    which size belongs in the 82 850 carbs ?

    1982 GS850 carbs used 40 pilots. Were all the mains the same? They should all be 115's. I'd check all the jets in that one carb. I suspect that someone has swapped out a carb in the rack from something else. Verify all the jets as you go. 22.5 pilots is crazy small. Don't know of any BS series carbed GSes that used a 22.5 pilot.

    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.

      Yes mains all the same, worse than that the pilot jet must have been drilled cause it has almost a 3/32 diameter hole in it !

        Just dump the pilot and pick up a replacement. I have some 40 pilots if you need one.
