I'm new to the forum after just having purchased a brand new 2009 crf450x. I've ridden 2 strokes my whole life, but was excited to hop on this beast! Took it out for about a 30 mile ride, and noticed that the idle was rough and changed pitch while sitting at idle, and also died on me just about every time i rolled to a stop with the clutch pulled in. Tried adjusting on the idle screw but couldn't ever get it right. Got it home and was pissed that my brand new bike wouldn't even idle right. Got on the forum and checked out some similar problems you guys were having. Ordered the JD jet kit and couldn't believe how quick it got to the house. I was a little intimidated by all the parts i had to remove just to even get to the carb, but I got it done and it wasn't as bad as i thought it was gonna be. Followed the instruction to a "T" and when the moment of truth came, she fired right up and runs flawlessly now with even more get up and go! If anyone is having trouble with lean/rich or idle issues I definitely recommed the JD kit. Thanks alot for all the input and hope maybe this helps somebody out!
