it might be your fuel screw which controls the low rpm gas mixture. i was having the same problem with one of my bikes and backed the fuel screw out and it was fine

Re: All YZ450 Jetting specs

2006 YZF450 (posted from Burned)

I can sya one thing for sure,the stock yzf jetting will be super lean at sea level.
This bike ended up with a 48 pilot jet a 162 main here at 5500 ft.
It will be able to stand a 158 in the summer.

At sea level you will need a 48 pilot and 170-172 main jet.
