The fact that they don't come with oil coolers is more astonishing to me. Air cooled motors are also oil cooled motors. Almost every air cooled engine from most major manufacturers comes with an oil cooler on them, even if it is just a little one.
The CG motor uses a large portion of the oil pumped through the system to cool the cylinder head. Plus, oil starts to break down and oxidize as well as lose its viscosity and lubricating capabilities if it gets too hot. The ideal oil temp range is around 180-200 degrees in a piston engine.
