yesterday was incredibly humid and bike wouldnt start, so i messed with my air/fuel and it eventually started. is there any way to know if im running too rich or lean? is there a good way to start? like twist the screw all the way right and then work back to the middle with a few twists or something? runs ok now, but i fear f*cking my motor up due to a bad air/fuel ratio.
