I know this seems odd, but one of my 372s I built this spring, I weighed all of the pieces to get the lightest parts possible. The chinese half wrap was a few grams lighter than the oem half wrap. So on she went. Its running mostly jonsered 2071 parts, with a later 372xp flywheel that has more fins on it and weighs a tiny bit more, but also moves more air and thus more cooling. Its meant to be the lightest ms472 you have ever seen. ha ha.
