it sounds like it is running lean around those rpm's, get a new jet kit and try re-jetting it, also on the left side (sitting on the quad) there is the mixture screw, look on the right side, if there is an adjustment screw on that side, turn it out about a full turn and see if that helps it any (but i dont know if it would have that screw)
