Drill main jet to 150, replace .10" spacer with .043 washer, pull brass plug to adjust low speed jet. The next time I feel ambitious, I will pull carb slide and fill space under the slide to streamline air flow. The carb or airbox or muffler mod by itself is not going to give you much, but altogether the effect is very gratifying.
