Engine casing crack

The crank casing is cracked :(( after the chain derailed on the front sproket. :bang head:
After I took of the heads I found the pin-bolt that goes through the con-rod was missing one clip!! Very lucky the pin-bolt didn't move into the cylinder-wall

Cylinder and piston

One of the clips that holds the pin bolt in place have started to move and disformed the groove and then jumped out into one of the ports. This must have happened when the piston was going up and the clip has gotten down into the crank where it has found it's way up on the other side of the piston. So I got both sides of the cylinder brused.
