The bike blew up a couple laps into the moto. He actually had no intention of racing that bike, he brought a brand new 2012 KX450F to tech and the AMA told him to take it home, wasn't legal. Kawi hadn't submitted the bike for the homoligation rule yet so he was forced to unload the YZ. Thankfully it wasn't a newer YZ because those aren't submitted or legal either even though it's the same freaking bike.
