No reason to stop. They don’t actually make the all parts – vendors do most of them. And as for Toms favorite “out of production” motorcycle engine, I’d bet that all the parts are made to Honda specs by outside vendors. All Honda has to do is manage the process and that’s something they do with all their products. No new engineering costs, very low tooling costs, just some accounting and processing costs. As long as the demand is there and the parts are selling (and they’re making money) why stop?
