Cuts out and sputter in a wheelie

What's up everyone! I'm having a little trouble with my 04 raptor.. she always runs great except when I get the front end up into a wheelie. Once the front end is up it starts to sputter and cut out but comes right back as soon as the front end comes down..? I have no idea except for the suspicion that it has something to do with the carbs.

Need to determine whether it is richening or leaning in a wheelie (try wheelie with the petcock closed and see if it gets better or worse as the carb bowl empties.) If it gets better, lower the float bowl level... if it gets worse, raise the level.
