Cases can crack. Look around the front sprocket. That's the common spot. Also where the rear end plates bolt to the case (just behind the front sprocket)to make sure the bolts haven't came loose and wore/broke the cases.
Frame: stand it up and look where the 3 tubes come together. Also the 2 tubes that are sorta beside the carb.
Hopefully the stock pipe comes with it.
