I am still mesmerized by jetting and need some help :worship: . Here is what I have:
96 KDX 220 - FMF Gnarly Pipe, FMF Shorty Power Core
Air Box Lid Removed, NGK B8ES Spark Plug
Jetting - Main 142, Pilot 38, Stock Needle In Second From The Top Clip, AS About ¾ of a Turn Out
135-PSI Compression
75 F at About sea Level
Gearing Stock
Now here is the question: why is the bottom end so tame? I would say it almost feels like a lean bog but it only starts to go away by making it leaner? On top of that it wants to let out a slight backfire when you let off the throttle??? I do not want to go leaner because of the clear consequences. The plug also has a dark ring at the base but I not have a good tool to view it other than a flashlight.
With my limited understanding the pipe is supposed to be geared for the low to mid power enhancement. None there when compared to a stock KDX220 I rode the same day. The jetting also seems lean by the other posts I have read.
Thanks and waiting to ride another day! :thumb:
