Not any more, they have to be water cooled due to the enormous heat generated by such high power outputs. An air cooled donk would just melt!!
My sister's VW camper, is definately air cooled!! I don't see any potential probs as the engine is mounted at the back in an enclosed space without a huge amount of cooling airflow, but as it is such a low powered engine she has never had any over heating issues with it.
