Arctic Cat Anyone know of issues with valves failing in the x motor?

My 2015 x motor failed at king of hammers, i wasnt even on the gas at the time it failed. I'm just asking to see if there is an issue with them amd or a fix for the issue. The valve that failed was the front cylinder intake valve. Head is toast, piston broke but cyclinder came away unscathed.

Its a sintered valve issue - fuel, jumped timing, or just age can cause it. Lots of deals on heads and what not out there to be hand - you'll need the head and valve cover - they're a matched machined piece.
