2001 yzf426 Jetting

My 2001 YZF426 has a White Bros. E series pipe. It seems to be running a little rich. I have had to change the spark plug twice in 3 months. I am not sure if the pilot jet was ever changed. It is hard to start when cold, but starts great when hot. What Pilot jet should I be running? Thanks

do a search on the yz426 jetting. You will find a lot of info on the topic.
