jetting specs yz250f 2010

I have tried to look through old posts but had no luck..

does anyone know the best jetting for my 2010 yz250f for say 0-1000 ft altitude and say between 40 and 55 degrees Fahrenheit?

any other info will be helpful

thanks

Stock jetting is pretty good. What issues are you having? If the bike runs fine, then leave it alone. Jetting changes when a bike runs fine yeild nothing.
