just finished the top end on my 97 kx250, started break in, has a bog right off idle. its about 30 degrees,, i have 170 main jet, air screw 1.1/4 out 32.1 yamalube 2R, i know its rich cause its spooging. i'm new to 2 strokes, i went through some old forums, and cant figure out how to adjust the clip position. if someone could give me a starting point that would be great. i have a pro circuit pipe and silencer, delta v-force, reed valve. Thanks much!!
