Hey guys, thanks for the honest/biased replies.
I'm not really trying to make the motor run like something else, just want to clean it up a little.
I will probably see if I can get a couple sizes smaller main jets and see if I can at least get the needle back to the middle of the clip. I'm guessing that if I don't like the way the bike runs after that it will be time to try a different needle.
$36 dollars is pretty reasonable for a jetting kit. I know I could spend that in a hurry if I started experimenting with different needles and considering the lack of knowledge that I have on the subject it would be like throwing darts in the dark.
I think the rb carb mod is what I have read about being popular with KDX owners. Not sure that is the direction I want to go right now. Cool to have the option though.
Thanks again, Derek
