Care to explain this? Are you suggesting Norton changed the balance factor when transitioning to the Commandos to save material costs?hobot said:As all the solid mounted vertical twin use BF rather higher than 50% I hold that Norton picked the BF that used the least costly metal in cranks yet could still be isolated by the amount of rubber area supporting the mass.
You know we are only talking about maybe a few ounces of cast iron flywheel material. Any cost offset as a result of reducing the flywheel bob weight mass would certainly be more than off set by the energy and other costs of making that adjustment (machining, grinding and/or drilling).
