Die Cast engine cases

[Hawkeye]

I haven't studied a new Gasser up close, do they still have sand cast engine cases? Big potential weight savings to be had if they are still sand cast. I weighed a clutch cover off of a 2002 300XC which was sand cast, and then weighed a die cast one off of a 2005... The sand cast weighed 12 oz. and the die cast weighed just 8 oz. I was surprised at the difference, it was just a little clutch cover. Imagine a couple pounds could be saved on the center cases by getting them die cast. Then there is that swing arm, it is really thick!
