200 enduro 84' yamaha

[fordman90]

Alright im new here, i figured you would be the guys to ask about this. My dad owns a bike that broke a few years ago,its a 198(i think) 200 enduro 2 stroke. He tells me that he was just out riding normal and there was a sudden clunk from within the engine, he them pulled over to the side of the road. He said that there was loss in power but the engine did not stop running. A few weeks ago i rolled it out and try to turn the engine over, it would move a small amount only I took off the plug and stuck in a plastic string thing and felt the the piston was in fact moving a little. I went back again a time later and the piston did not move at all.What do you think it is, what should I do?
