Dick - I am with you on oil. I recently went from 100:1 to 32:1 in my gassers and they wear longer, make WAY more power and run cooler. I am converted.
My reason fro the low oil parts is not to use low oil (well maybe a tiny bit less like 15%) but because from Chad's description it sounds like they have made a spiral channel that gets more oils to the cam gears. In a YS (or any 4-stroke) that can only be a good thing
