jetting question (newengland area)

[stinx]

I currently have a 02 KDX 200. The bike has a FMF Gnarly(torque pipe) and a turbine core two silencer. The air box lid is in place. The bike currently is jetted stock.What are the jetting recomendations for this set up?

I live in Mass and I run a 155 main and a 45 pilot and fine tweak the air screw. I have a PC pipe/silencer with the air box removed. with a set of boyesen power reeds. I run Maxima Super M premix at 40:1 with no problems. You may be able to go leaner but this is a great starting point. Hope this helps.
