NEW FMF Fatty PiPe and Carb Adjustment

[mlhend1]

I recently received my new FMF Fatty Pipe for my 1994 KDX 200. I have noticed it is running more rich, esecially at low RPM. Should I just turn the air screw out a quarter of a turn at a time and check the Spark plug for running condition or typically does ne have to make needle/pilot adjustents?
