Hy HevyHauler, I don't mean to throw a wet blanket on things, but when I opened your link to the bolt on flywheel weight, I noticed they were talking about aluminum flywheels. I would just like you to confirm that that is enough weight to balance a large iron flywheel, also the two different design flywheels are quite a bit different in diameter, and I wonder if the weight placement for the smaller and obviously lighter flywheel will be correct to balance the larger and heavier flywheel. I just don't want anything to go wrong with this installation, so please verify this weight will do the job.
