Thankfully, I've never had to bust the bike down enough to actually see the flywheel (yet) and I can't determine by looking at internet pics if this is even possible....so, I'm wondering if anyone's tried to lighten the stock flywheel, whether it be from being milled down to punching lightening holes in it? As always, I'm trying to be a do-it-yourself'er and save a buck or two where I can (sorry TT, Uncle Sam doesn't pay too well!) and being that I've access to a machine shop, thought it might be something to look into. Was just wondering if it could be done and, if so, what were the results. Cool!
