It's all in the cam.
They just change the cam grind so that the exhaust valve opens on the intake stroke, and the intake valve opens on the exhaust stroke.
It's not very efficient without major head work, because exhaust valves are much smaller than intake valves. I can't see any reason for it except for visual impact.Jack
