Anyone, please correct me if i'm wrong, if you have a lightened flywheel you will know what I am talking about.
Please, please do not put your life on it. The flywheel has no affect in any way shape or form on the gear ratio. 1 rotation of the crank will always = 1 roation of the flywheel, no matter how much it weighs.
