I was on a trip and i was doing agout forty miles an hour when a log more or less came out of nowhere and i hit it hard enough that it ripped the handle bars right out of my hands and then some. The question is, is that if the atv has a much greater turning radius to the left now and hardly any to the right, does anyone know what the problem would be and what they think it would cost to get it fixed? And it is not the tie rod because i had checked those out and they were very straight, no bends at all. THANX

 

It is quite possible you have bent the frame, I've seen it before. Cost, expensive.
Make sure you check everything else first, steering stem, tie-rods, control arms and mounts etc.
Good luck
