    Rebuilding carbs...

    When ya rebuild carbs are the jets and needles supposed to be bottomed out or bottomed out and then turned back a certain amount? Ive put new jets in mine but cant find anywhere that specifies this...

    its a gs650

    there is only 1 adjustable needle..the MIXTURE SCREW situated at the top rear of the carb throat in the tower. You turn it in SLOWLY AND GENTLY. Once it stops dont force it any further. from that point make a mark on the rim of the tower and turn it out 2 1/2 to 3 full turns as your initial starting point.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

        Main, pilot and pilot air jets are bottomed out and snug. As Chuck said, the adjustable enrichment jet should start at LIGHTLY bottomed and back off about 2.5 turns as an initial starting point. That adjustment jet is located behind an emissions mandated plug from the factory. Get the online rebuild tutorial and READ IT. It will tell you every detail on what is needed.

        Darn, with so many daily riders it's hard to decide which one to jump on next.;)

          Am betting the "dont (F) with this screw" plug has long since been removed. Just look at the top rear right behind the top cover of the carbs and youll see the slotted screw down the hole.

            Could be, but I still find tons of carbs with those plugs still intact. When I pick up old grunged up carb sets for resale I like to see those caps still intact. Much easier to deal with then the ones that have been seriously buggered up by some hack.
