To briefly put, my brother an I were out riding (I was on my bike, he was On my quad).. He thought it'd be fun to beat on it, and flipped it over completely. He's fine, but the bars are bent up. It started up and ran fine back to the house! But I'm concerned, and also pissed.. What should I check?? Was a mint quad for its age. Thanks!

 

Sounds like you are out a set of bars, and probably a steering stem also if it was stock. Other than that, I would check your controls and perches, wiring harness and cablessed routed near the damage, tie rods and ends. That usually does it.
