So I understand the concept of reed vavles on case inducted engines; when the crank case is under vacuum, air/gas are inducted, and then when full, the reeds close and allow the case to be pressurized, so that the air gas mixture is then injected into the cylinder on the down stroke. More efficient = more power and rpms.
So, is there any argument for reed valves on cylinder inducted motors? I was intrigued by the recent post in Buy/Sell for a franco morini kit that is cylinder inducted and has reed vavles.
