What size pilot jet to use. 48 or 58?

I'm running a YFZ450. Lrd full pipe kit and K&N. 150' above sea level and 20 degrees outside.
Should I be running a 48 pilot jet or a 58 pilot jet?

I would think the 48 would be much better. I've never heard of anyone going above 50 for the pilot.

Thought it was strange to go from a 42 Pilot jet stock to a 58 Pilot jet. Awful big jump, eh?
