I had a banshee with a 4mm crank and bored .30 over with trinity pipes and I ran a 27.5 pilot jet a 320 main jet and the needle i moved the clip one notch up from the middle.I would say your probably will end up around a 320-340 main on stock carbs with either 27.5 pilots or 30 pilots i hope this was some help for you.
