I'm swapping carbs on my 250ex from the stock one to either a ATC200X or XR200 carb.
I'm practically a pro when it comes to jetting, however, this is the first time i'm working on something that will have a bigger carb, etc than what it came from the factory with.
speaking in generalities, should i expect to jet up (richer) or down (leaner) after installing the bigger carb?
