Sorry to jump in here Fred.
Ryan, what has that link got to do with "pressure lubricated bearings"?
It even describes CCI (Crankcase-cylinder-injection) as injecting oil into the carburetor. I am sure that is a mis-translation and it actually injects into the intake tract.
I don't even want to go to the 2 vs 4 stroke argument. Personally I have never owned a 2 stroke that gave me the reliability and longevity of a 4 stroke, even with all those extra parts.
