A valve snapped and blew the piston into pieces
and the crank pushed the bits through the upper case!
A "snapped" exhaust valve
The carburator full of aluminum scrap...
...and so was the cylinder head intake.
I found these parts (of a piston) in the exhaust system
The spark plug looks really healthy!
Does this intake valve need an adjustment?
What about the exhaust clearance? ;-)
I think I need a new head...
...or at least "some" polishing! Haaa Haaa!
The wrist pin took some heavy load...
...and the sleeve had a rough time
The connecting rod was bent but still in one piece!
Damn Damn DAMN!
