timing chain busted
 

whats up everybody, i was riding my scrambler 500 around yesterday and when i came to a stop my motor made a really big clunk and thats it. i cound pull it over and the starter woudnt turn it over. after tinkering with it i finally broke it loose. after messing with it i finaly found out i broke a timing chain when i pulled off the cover on the side of them motor. did it do anymore damage than a broken chain and maybe a timing sproket? is this an interfering motor were the piston will hit the valves? im supposed to go to the badlands on friday with my friends so i really want to get this thing fixed as fast as possible, any info would be great
