Extra parts needed for carb rebuild on a GS850

[Anonymous]

I am in the process of rebuilding the carbs on my 1980 GS850GL. While dismantling them I stripped out one of the "Air Bore" screws, so I had to use an easy out to remove it. I wasn't sure what this was, and I got this description from the carb rebuild series here. I am sure someone here can tell me where I can get a new one, or a set of four new ones, or does anyone have one sitting around. If a better description of the part needed is required please ask and I will try an do a better job, or just refer to the carb rebuild series and look for photo 083.

What exactly does this screw do?

Thanks

Rebuild kits....

Two words......... Rebuild Kits. If you need O-rings + other parts just get the kits.

If you really want to fudge around with the old parts I'll send you an air screw + what ever else I can dig up that you need. It sounds to me like you need the kits. Did I meantion kits?

Does the kit come with this screw?

I have seen descriptions for kits that contain the air mixture screw, but do they include this one as well? What does the AIR BORE screw do?

It's for the pilot.

It meeters the air flowing into the pilot/idle circuit. The pilot draws air from that screw, and fuel from the little hole drilled between the pilot and main jet.

At idle when the main bore/butterfly valve is closed the pilot supplies fuel/air to the air mixture screw. The little tiny holes under the air/mixture bypass the butterfly valve to allow the bike to idle.
