i bought a 2002 YZ426f as my first dirtbike. on the first ride i dropped it, then it began to leak coolant. i stopped riding it and and managed to get it home. were i refilled the coolant on it and let it idle for a while. when the coolant level remained constant i took it for a test spin to see if it was just some freak accident. it was not. i seized the motor up. (Dont know why i thought riding it was a good idea)
the top end seems fine but the cylinder is fried and so is the piston and tie rod.

anyway when i removed the oil coolant came out has anyone had this problem if so what is it?????

Thanks so much
