what is the stock bore size of a 400ex and what is the 440 bore size? i just got a used ex that is smoking a good bit and i'm going to tear it down in the next week or so. It supposidly has a 440 kit but i'm doubting it. i just wanted to know what the cylinder size should be so i'll know what i'm looking at when i tear it apart.
