JD jetting Wr250f

Just wondering what JD jet settings people have settled on. Bike is a 2013 WR250f. Tried recommended 185 main with red needle 4th clip and way too rich. Did oring mod and installed #60 leak jet supplied which has really improved initial throttle response and no bogging. Pilot circuit is ok ( 45 ) but needle and main settings are shit. Iíve heard using red needle 4th clip with stock 170 main is the go. Anyone found the sweet spot combo.
