[QUOTE="adam728, post: 1413224, member: 55463"] My thoughts on the o-ring vs head gasket thing. O-rings are nice in that for manufacturers as they take some tolerance stack up out of the system. You are always seating the head directly to the cylinder, and you don't have to worry about a gasket being 0.032 +/- 0.004 inches (so one lot of parts might be 0.028" thick, the next could be 0.036" thick). The second advantage to o-rings for the manufacturer is cost, they are dirt cheap, stamped gaskets are not. On modern bikes I bet a pair of o-rings costs the manufacturers something like 15-50 cents per bike, where a stamped gasket might be $2-$7. Everything is engineered based on cost now days. If you can take $5 out of a product that you build 5,000 a year of, well, that's an easy $25K extra for the company. I've watched engineering changes that cost less than a penny get shot down based on cost (adds approx 0.25% cost to the part). Of course, when you are building millions of them a year, it adds up! Just my opinion on why bikes now typically use o-rings. [/QUOTE]
