    How can I remove a messed up pilot screw?

    I managed to booger up the end of one of the pilot screws. Is there an ez-out or something similar that I can reach down there with? It is such a small hole to begin with.
    I have to get it out.

    Never done it myself but some have had success with an easy out or a left hand bit and HEAT. The heat I think is key. But the easyouts are scary to me. I don't like em. If you can get pruchase to it with a long skinny center punch or screwdriver and give the edge of what's left of the slot a good couple raps with a light hammer it might break it loose to get it out. Good luck! If ya end up screwed i know someone who might have another bs34 for your KZ that I could pick up for you. Lemme know.

      George, I would also try the LH bit and heat first before the easy out. Can you get some PB blaster or Deep Creep in from the inside of the carb or is the screw bottomed out?

            It turned slightly before I boogered it up. I then dipped it for 24 hours hoping that would loosen it, to no avail.
            Where can I find a LH bit?
            TCK, it is a BS34SS that only came in the 82-85 GPz 750s. Is this what you are referring to?
            Thanks for the ideas, BTW.

              Had a problem where my mixture screws were all goobered up. I went and got a 3/32 engraving bit for my dremel and made the slot deeper into the screw. just enough so the screwdriver could grab. Heated it up a lil and came right out!

                Bs34 is a BS34.. unless they did something special?? Take some pics of the jet area, bowls etc.. If its the same as a GS, (which im pretty sure it is, Mikuni didnt do anything special aside from the port spacing rails that *I* am aware of for a GS or KZ/GPZ, and speaking of, you sure its a 34 and not a 32??? For some reason i thought you had a GPZ11)

                        Here is a quote from Robert Barr: "I've never seen these particular carbs before." Not really an inspiring email, considering I was too far into them to stop at that time. Not his fault either, this bike is unique in many ways.
                        I'm still struggling with the o-rings, only half of them were correct. The air screw and drain screw are different (and the choke plunger, which had no o-ring at all). Nessism worked with me on that, I now have o-rings for the air screw.
                        Quite certain they are BS34s.
                        The KZs of the same era used Keihins.
                        I'll post some pics as soon as I can.

                          Got it

                          You guys are awesome. While this was going on, I had placed the carb in the oven to bake on the black engine enamel paint. Since you mentioned using heat, I pulled it out and placed it on my bench (using an oven mitt, of course). With some invective, time and effort, I got it out.

                              Hey, I'm stilll learning. This is my first go-round with CV carbs. The last carb I worked on was a lot simpler, and was attached to a 1973 RD 350.
                              And yeah, I'm not saying I go to HF a lot, but the manager does know me by my first name.
