That's a pretty cool illustration!Eminence vents in front and back on the Kilomax Series, so I don't think they're opposed to that sort of thing. They also have radially spaced holes on them rather than a single large vent as other models do. But I think they're planning a central rear vent on the new motor. I don't know; They're still looking at it.
Summer is pretty much June, July and August for we Americans. I'd love to spend spring and summer here, and then "fall" and "winter" there!
