needle advice

[skippyjlo]

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
