Oh well, These things do happen. As it happens, there is considerable 'overbuild' in the 'fan capacity' of these flywheels. From a Fluid Mechanics perspective, that is.
So it may seem counter-intuitive; but the best thing to do is, to knock off the diametrically opposed fin; this maintains the dynamic mechanical balance of the flywheel, and won't affect the 'fan capacity' appreciably.
