Hey I'm really sorry that I haven't answered this earlier but I have just only seen it, plus I haven't been on this forum for a while...
As for your question, if you only do the holesaw & baffle mod, you shouldn't have to make any other adjustments.
But in saying that, Honda do run these fairly lean and you might think about adjusting the idle mixture out a 1/4 of a turn to see if it makes the bike a little smoother.
But this isn't necessary if you only do the mod and it runs and feels fine.
Again, sorry for the late reply... Hope this helps you...
Hello soxOZ, My 2009 Shadow is not fuel injected . . . will that make a difference in whether I would need to rejet or adjust my carburetor with the holesaw mod + a baffle mod similar to your elliptical baffle mod?
