No argument from me on that point.
What I have found easier, is to add to their systems rather then to replace it.
Thats why I fitted an extension sump from Volkspares, and a small scoop which I will later take off when she has fully run in.
The extended oil sump, gives extra cooling and reassurance that you have more oil in the sump so you will not run short on a long run.
By fitting a Oil temp gauge and a rev counter, I have learned that the aircooled motor cooling ability is best at 3000rpm.
The minute you get over the 4000rpm mark, the cooling/ heating ration goes to
Now when I work any of my aircooled hard, I take it back to 3000rpm, for a few minutes and it cools right down.
Hope you find what you are looking for.
