	Damage due to Missed Shift
	"After removing the head on number 1 the noise became self evident. The lower part of the broken valve is embedded into the head, the valve seat is nowhere to be seen (most later found in the muffler) and the top of the 10.5:1 piston is munched (but still serviceable after a hit with the angle grinder)."
