2006 YZ450F Carb Jetting

I have a 2006 YZ 450F with stock header, FMF 4.1 slip-on and I am running ready air filters. I need to rejet due to leaning the bike out. I am looking at Dyno Jet Kit, any opinions on jetting specs?

Elevation 707 to 1447 (Mt Sterling KY)

Start with 168/45/needle in 4/2 turns out. You don't need a kit. (IMO)
