I'm no expert on this, but around 5000rpm is where the main jet comes into play so it sounds like you need to go up a size or maybe two on the main jet . This is often the case with aftermarket exhausts.

Just fitted new main jet size 165 as recommend on here some where. Old main jet was std size 152 slow jet is 48 so the Honda modifications to the carburettor(158 main 52 slow) and valve clearances have not been done .A job for the winter me thinks .Weather permitting will give the bike a road test tomorrow and report back with the results .... :)
