Hey fellas. I'm on an 04 450F and I've got a black residue in my tailpipe and seems to bog a little out of the turns. I'd like it to snap more out of the turns since the local MX track seems more like a supercross track (they ruined it). Is my jetting to rich? Everything else seems fine; starts pretty easy, only pops when on the stand.

main: 165
pilot: 45
needle: #4
starter: 72
fuel screw: 3/4 turns
altitude: 4500 ft - Northern Utah

Thanks for your help.
