Needle position change

With the addition of a FMF Pipe and air box lid removal my air screw adjustment is now about 1/4 out to produce a golden brown spark plug and perform properly. Is this a problem if the bike is running correctly? I am afraid with the weather getting colder in NC I will have to turn it in even further or not be able to. My stock needle valve clip is 2 clips down from the end (lean side), so i should be able to move it to a richer position. How many clip positions should I move down to get the air screw to be about 1 or so turns out? Please help !

Yes, my KDX is horrible to start when it gets cold. I have to tip it on its side at least a couple times and in gear, push back and forth. I will try dropping one clip postion and then make the appropriate air screw adjustment. Thanks for your help!
