I have a 2003 WR 450 and its having a bit of an issue right now. When the choke is pulled out, it will run/idle just like it is supposed to. If i close the choke, I have to bring up the idle on it and it is a bit rough. Could this just mean I need a bigger jet for air. I also just completely tore apart the carb and cleaned it so i know thats not the problem. If possible list jet size recommendations for certain altitudes.
