needle advice
Hoping I can get a shove in the right direction. I am trying to get rid of a hesitation around 1/4 throttle. The hesitation is basically right before it starts to come on the pipe. I can make it better by leaning the needle clip but it is making the power delivery really pissed off and I want to get rid of the flat spot but keep the tamer mid boost of the richer clip position if that makes sense..
Current set up is 2009 300ec 36mm carb from a ktm (flat top not screw top) , nedw clip 1, 40 pilot, 172 main, 1 3/4 a.s., gnarly pipe, PV shims removed Ideally I want torque, and a strong but linear power band. I have two other 38mm crabs, one with a divider plate in the outlet bore, various other needles but all different manufacturer codes. I am willing to try whatever but I get lost in the codes and variables. Hoping for a little help. Thanks in advance |

Given its a 36mm carb, I'd be looking at doing something similar to what the ktm folk do!
38 NECJ#3 or NEDJ#2.. Maybe 165/168 main jet.. Should be close. |

Okay, I need a simple refresher on clips and #'s. #2 is "install the clip in the second groove down from the top" of the needle, yes?

Nothin wrong with double checking.i had to recheck myself when i ditched the old 4t and got back to my 2t roots.also pays to remember the airscrew is opposite direction to a carb 4t!
