What Needle is This?
Posted: 10:29 am Jun 11 2016
I have a 2006 KDX200 that I bought with an FMF Desert pipe already installed. It came with this needle set in the leanest clip position. ( I dropped it 1 clip position) R1174K / 2AFKQ .
How does this needle compare to stock? Which of the 2 sets of numbers on the needle should I be working with?
I recently changed to a "Woods" pipe and am trying to tune it. The mid range was awful (lean) with the "Woods" pipe. Quite opposite of what I expected! I raised the needle to the center clip position and went up one MJ size (to 155). It runs much better, but is a little flat at 3/4 throttle-WOT.
update : I just bumped the MJ to a 160 and went for a ride. Wow! It made quite a difference. Much more and smoother power throughout the entire rpm range. I am amazed at how much more fuel the "Woods" pipe needs vs. the "Desert" pipe. This needle works very well at cleaning up the typical KDX rich burble at low throttle openings. I still get quite a bit of spooge. Even though I run a 50:1 mix. I'm at 3000' elevation at 65 degrees F.
