I put a 48 pilot in my 08 YZ450F. When it was colder out with a 45 in it I had to run the fuel screw at 2 1/2 turns out. Now that I have the 48 in it I tested it on a little bit warmer day and it ran the best at 1/2 turn out. My question is: As it gets warmer am I suppose to be leaning it out? Meaning turning the fuel screw in? If so then I need to go back to the 45 because I have no where to adjust to. Everything is stock except for merge AP spring and full FMF 4.1 exhaust.
