I was recently riding a wheelie, and when she came down it hit a little hard. And as soon as it hit the ground, quad died. Would anyone have any idea as to where to start looking? I have checked compression and fuel. I am getting both, but I hold the spark plug in my hand and ground it out and kick it and I don't get poked. I have taken all of the plastic off of the machine and it doesn't appear that there are any broken wires or spots where it is grounding out. Where should I start?
