Started by turning down the step
Then I cut away some of the middle
I just weighed it and it came in at 15lbs. This was my first attempt at lightening a flywheel so I was conservative with how much material I removed. I definitely know where the other pounds can be removed next time around. However for now I'm happy with a 21% weight reduction.
The flywheel and pressure plate are going to get balanced with the crank this evening.
