My R6 used to run rich, at least I think because it would spit carbon out of the can, so I installed a BMC filter thinking it would even it out. Well, now I think it is running lean. In first gear if I have the throttle all the way open, when it reaches 10000 it starts to studder and jerk like it's kinda running out of gas. I don't have this problem if I roll onto it a little slower and it's not as bad in 2nd but I can still feel it a little. So what can I do? Can I just adjust the pilot screw? How far should I turn it? Any help would be appreciated.

Oh, it's an 02 R6 with a D&D slip-on and the filter, nothing else.
