Hi. Just sent my 2MG carbs off to be cleaned. Should I think about altering the jetting as I have a K&N filter (standard airbox) and a 4-1 exhaust with ART end can? Any advise or thoughts welcome. Thanks Ray

Hi Skye high do u know if the jetting was done after the pipe was fitted in my experience when I went from std mufflers to a 4 into one my carbs desperately needed jetting all the best

Aftermarket exhaust alone is enough to upset the delicate fueling on the FZ so yes your jets/carbs would definitely benefit from being tuned. Mine field trying to tune out the dreaded 4k flat spot which you no doubt now have. General opinion is nothing short of a rolling road session will get you close to having an acceptable power curve but be warned, There are forces at work with the standard set up that can never be emulated once you mess. Good luck, you'll need it!
