do they move/slide on the fingers or do the fingers move? I get the fact that the thin spring is there to keep them circular and it would have to allow the whole 'ring' to expand with the fingers (the weights spreading out along with the fingers) but I would expect a fine piece of engineering (product of the year, etc) to at least relax to a static state that could be repeatable. I guess not from your hands on experience. That's not good. Id also expect the ring of weights to stay circular, equidistant from the crank centerline so the balance would not change through the operating range. I guess well never know unless you pull the trans and start it up without it.
