Tell me more about needles
Posted: 04:03 am Apr 02 2015
I'm trying to clean up my KDX's jetting but I'm really struggling to achieve smooth power delivery throughout the rev range.
The bottom end power, according to me, is fine. I have never done a plug chop test to check the main jet, but I'm happy with the top-end power.
The big issue is the mid-range power delivery, it sucks balls!
Now my question is should I change the needle in order to achieve a smoother mid-range? Will I be able to fix the issue by changing pilot/main jets?
I know the bike is jetted too rich because after a long ride with lots of half throttle operation the bike spooges everywhere.
Currently I have a BFQ needle in the bike which I believe is quite a lean needle.
Also running a 38 pj, 152 mj and 1:40 2t mix riding at 4000 to 5000 ft
