let mushroom_toy drill them out.......or

get the FMF power-up kit...it's a stage 1 kit that comes with 3-4 different main jets for the different exhausts, new pilot jet and needle. move the clip to the middle of the needle (down one) and you'll be cherry....assuming you are going with a decent pipe.

if you are uncomfortable doing it yourself bring it down to suzuki of atlanta and we'll knock it out....but we don't work for free.
