engine noise

could be top end or the upper or lower connecting rod bearings, does it slip when its in gear? i would say is probably say its something around the crank or bottom end, did you take the cyc. head off yet?
 
i just took it apart and my piston is broke and now theres pieces of metal everywhere.my crankrod bearing is a lil play in it.im just gonna go ahead and do it right and put a 3mm stroker crank in it with a new weisco piston kit.
