What's the difference between the two Factory Pro jetting kits in terms of the contents? I know one is geared for bikes with the stock airbox and one for bikes with the airbox removed. Do they come with different jet sizes or is there more to the story? I don't want to invest in one if I'm going to remove the airbox shortly down the road. I guess it might be easier to do it all at once, but just weighing options...
