I understand these to be very "top-ended" motors. The powervalves are not active, so what you're getting are the modern port layout and transfer design. I don't know if they're any better or worse than the Pro-X or Duncan cylinders.

The CR250 powervalve is driven off the crank. It's virtually impossible to get it working with the 250r bottom end.
