I'll chime in on this one too. I have received my yellow belt (newb) in production. Yes, its much more cost effective to produce a couple thousand price/unit than it is to make a 100 of the same. I can tell you that two stroke molds are much more intricate and difficult to get right, than a big four stroke mold (got a bit of time spent in a couple of foundries). Machine time, there are a few machinist on this forum, ask them. My little cylinders are not easy to machine (with any quality) and a big v8 is not much harder or expensive. Its mainly volume. But try to buy an equally built v8 and see where the price is, performance marine v8's, not so cheap.
I wish it was more like 102nd7's explanation, at least for me.
