Are you running larger tires or stock? I think you have to be hard as hell to smoke the wet clutch. I've ran tracks with the factory belt and wet slugs for well over 3000 miles and my grizzly still runs strong.smoked the wet clutch with only 80 miles on the unit. Was not covered under warranty. Yamaha corp said it was a normal wear and tear item. The only time the machine was put in high was on large open pastures other than that it was always kept in low.
