What is the factory fuelair mixture screw on a 1979 GS1000?

Hi Bud Maybe we can help each other, I am having the same problems. Mine are now set to 1 turn open which is running rich enough to start and run smoothly without choke, but runs very lumpy when warm! I'm not sure now whether to go in or out from here? My air screws are about 1.5/ Cheers Chris
