most likely, however if the restriction is the same, you should not need to.

Unless the exhaust is completely open the answer is generally no, it's when airboxes are changed or when pods are put on that jettings are changed, though that said my own stateside KZ has a 4 into one and I changed the jetting slightly on 26mm pumpers to suit the UK conditions.
