hey, this weekend i was just riding my 2001 yz426 in fourth gear and all of the sudden my bike seized. so i go back to the house and rip it apart, and find that it didnt actually sieze, the valves blew up inside the engine and one even got lodged into the top of the piston, the entire top half of my engine is blown up into shreds and pieces. i really dont know why all of the sudden my bike does this. it has never had one problem in the 16 months i have had it. i change the oil and it had plenty when i drained it to take it apart. i had engine ice full to the top. i have checked the timing on it a while back and it was perfect. it has always started first or second kick, literally. now i am completely screwed because a big anual glamis trip is coming up in a month and i have no bike, and no money to fix it. can someone please give me a direction to go, for a college student!!
