At least with an aircraft application there's lots of high speed air compared to an ATV. This problem of cooling capacity is very real. Many Himax builders use 4A084 generator engines and I have read several accounts of attempts to increase the HP output that immediately ran into CHT problems.
Now, if someone was offering water cooled heads for the V-twins like Rotec does for jabiru engines.......
