i have a rm85 with a Keihin PE28 i need to know which way to screw the screw to make it richer in or out ? also if you know what it comes set at from factory that would help also.

thanks

screw it in for less air turn it out for more air, you might need to change your pilot jet depending upon if its rich or lean.. what foshezy said
