Use the gear oil in front and rear diffs.
The Mobilfluid is used in the Kodiak 700 because it has a wet brake in the rear diff assembly. Regular gear oil cannot be used here because it will damage the wet brake.
Yamaha more than likely just did a copy and paste when making up the new owners manuals for the newer Grizzly and Kodiak's.
Checking the valves properly requires taking a measurement using a feeler gauge at the rocker arm. So it requires taking off all the stuff in order to do. If the valves require adjustment, with the newer 708cc engine, even more stuff has to come off. It's a labour intensive check.
