Re: lightened flywheel
You don't say how much it's been lightened. I think the amount is important. In the days of Mod. A s, a 63 lbs FW was more useful than today. Gas wasn't as good, roads were rougher. speeds were slower. Engines needed to store the energy. Today the energy needs of an engine are different. A lighter flywheel means that speeding up the engine doesn't sap the same energy from the piston stroke, but conversely, 40 lbs of rotating iron doesn't store as much energy as 63 lbs. So it's a trade off. I have lightened my FW to 53 lbs and I'm quite satisfied with it.
