Did anyone tell you that the Kawasaki racing head gasket uses a restricted oil supply passage up to the head (smaller hole in it). You can also restrict the oil supply to the trans and clutch if you don't plan on spending a lot of time sitting around in traffic.
Watch out for them oval shaped main bearing bores. If they want to sell you a motor without a flywheel or stator cover look elsewhere.
