It's actually a system. Just doing one or two of the mods won't work all that well. You need to do most of it, if not all.
Cut the airbox, remove backfire screen, get a high flow filter like Uni or Twin Air (better to go with the Twin Air Powerflo filter because it has a fire retardant layer.), do a bafflectomy or remove it all together, jet correctly, o-ring mod, and get an easier to adjust fuel screw. Do all that and grin.
