Now you have me worried! I don't have a pic of the lifter piece but I thought that 2010 was the first year of the new style. If anyone would know it would be you Warp. I think it was the new style. It did look like new though. No burn marks at all.
I'm not confused about how the springs function but I may have not used the correct terminology. I think that you may have misunderstood what I was trying to say. When the crank gear is meshed with the gear on clutch, the pressure from the backlash eliminator spring pushing on the teeth is what causes the two gears to want to push away from one another.
I know that you don't like my way of balancing the hub and I would have preferred a couple of tack welds if I knew for sure that this was going to work but the point of the matter is that the clutch hub was obviously out of balance and was a definite reason to cause a vibration. My math is a little rusty but I did calculate that the weight of my washer at that radius would exert a force of about 10lbs at 2400 rpm and 36 lbs at 6000rpm.
