Also, cartridge size must be taken into consideration, a larger cartridge , as on a late model Yamaha KYB which is 32mm has much more "swept volume" than on a late model Kawasaki KYB that has a 28mm cartridge. We can compare these two because they have the same piston rod size.
The midvalves in these forks are set up night and day different, the Yamaha has about 1.5mm float versus the KX which only has about .1mm float(actually it is more of a bleed, because there is a 13mm dia. x .1mm thick shim under the sealing shim). But they work very similar beacause of the different cartridge size, if you put a KX style midvalve(.1mm float) in a YZ fork, it would be very harsh. In the same respect, if you installed a YZ style midvalve (large float) in a KX fork, it would almost act as if you have merely a check plate.

Lets say a piston moves 1 inch in a cartridge full of fluid, the piston would flow through the "same amount" of fluid wether it had small or large ports.
