[QUOTE="MotoBK, post: 1381936, member: 116083"] 2001 KDX 220: 42 pilot, 145 main, Clip in 3rd position from top. I recently did a wiesco Top End, and Boyesen Power Reeds. I now have bogging(I Think) from 3/4 to Full. It just hits a bog wall and the engine will not rev any more. If I turn the air screw from 1.5 turns to 2.5 then the top end comes back....and it runs strong again. I bought a 142 main, and threw that in it seemed to make things better at 1.5 turns....but I was told that is a bit to lean. I know the process to figure jetting by starting with the pilot...then working to the needle...then the main. I tried droping the needle to the fourth position....and that made things worse as well. I just wanted to know if this sound straight forward to anyone...as far as the way my motor is responding. I cannot tell the difference between a too rich bog, and a to lean bog. Any advice is appreciated. [/QUOTE]
