    cv carb air screw

    I'm pulling apart the carbs on my 1980 GS850 for the first time. I've been using the GSresources guide on carbs. Well, I got to the air screw and it is different than th photos. No slot for a screw driver--just a pinhole. Any ideas on how to remove the air screw? I'm at a loss...I suppose I can just clean the carbs without removing the air screw???

    That's an aluminum cap over the screw. Take a sheet metal screw and screw it into the cap and then lever the cap out, some people drill the cap first. Be careful to not go too deep though the cap if you drill.

        Thanks, I'll give that a try.

          how deep does the cap go? I've strated a screw and the cap isn't coming out. So i've drilled a bit, but don't know how deep I need/can go?

            It's about 2mm thick, there is a small space (2 - 3mm) before the screw itself. I like to twist the drill in by hand to avoid going too deep.
