carb tuning ?

You will hit a point where turning the screw out will not make the engine rev any higher. Find this point then turn the screw back in until the rpm just starts to drop a little. This is how I set my coarse a/f screw position, I then fine tune with the ride&feel method.

When the pilot is set it should be between 1 and 2.5 turns out, though some kdx'ers including myself have used settings around 1/2 to 3/4 in the winter.

If you find the ideal setting is more than 2.5 turns out then you may want to try a smaller pilot.
