So let me get this straight.I can buy a Novarossi P5 built with all the expertise of Mr. Rossi.It would bebuilt using all the resources/money/experience thatMr. Rossihasto be as good as possible. Then I could get this gem modded by a<font size="2">reputable</font> enterprise and it willbe much better. It will have more power and more mileage and no downside. Doesthis really seem reasonable?

Changing port and crank timing and their interaction should be second nature to engine designers(Rossi, Roem, etc.). Any combination to timing that a modder produces can be duplicated in a factory. So why don't the factories match the specs of themodders?A port is a port. Easily cut on a CNCmachine.
