John, your right, it's no sweat to dig through years of engine balance cards but it is time consuming and time is something i never have enough of. It just isn't worth it. as i said earlier in this thread, we'll just have to agree to disagree.
Oh, and yes, i would never just throw in a factory replacement crank without balancing the rotating assembly. They were'd that good from the factory as it is, why add insult to injury?
