[QUOTE="lemmy, post: 1315447, member: 93740"] I got the idea to try the CEL, CEK, or BEL needle from Gearloose and this thread here [url]http://kdxrider.net/media/CC.doc[/url] it is a long thread about people trying different jetting on their KDXs. I was confused at first becuase I knew the stock needle worked ok and it is a B taper. But the more I thought about it and using JDs spreadsheet to look at relative jetting [url]http://home.att.net/~wbarrow/jd/JD_Jetting_2002_VS.zip[/url] I was convinced and gave it a try. The 1174L is a taper of B, diameter of Q and L1 of between F and G (no direct translation for the L on the oem needle). So If I say the stock needle is a BFQ and I use a pilot of 42 and I compare that to a CEL with pilot of 35 you see with the spreadsheet that with the exception of just off idle and between 1/8 and 1/4, the CEL setup is just a bit richer. The L diameter is smaller (richer) so this is why I use a leaner pilot. [/QUOTE]
