The only thing Kohler really ever recommended after going to full pressure lubed engines with oil filters was several years ago when they were seeing some flat cam lobes on their Command engines. That really has nothing to do with your 7000 series but a lot of techs started doing this break in procedure on all Kohler engines. It was to run the engine about roughly 1500 RPMs for 5 minutes. After that you would run as normal.
Back when engines were splash lubed with no oil filters, Kohler recommended running the engine for 5 hours then changing the oil. Some who have been around long enough to remember the K series engines still do that today.
