Actually amazing how little damage has been done.
How did this happen? Any 'clues'? Do you run a head temp gauge?
This was cylinder 1 right? Usually one of the coolest running ones...

Thanks for sharing.

valve float and not enough deck hieght!buzzed the engine to about 7500rpm with about 2mm deck hieght.lucky i was changing gear when it went so no load on engine and as soon as i heard it let go i hit the kill switch.crank and rod are perfect just goes to show how strong typ4 stuff is.
head is off to be welded tomorrow so should have it back to be remachined and checked by the end of next week,just got to decide weather to go for stronger springs or limit revs to 7000rpm[220lb installed]and what retianers to use?think the valves era trw stianless but would like to try some titanium ones if i had deeper pockets.
cheers rob
