Not mine, fear not. It's just been a question that's asked here now and then, and I've never seen anyone post of photo of the results. A local Duc specialty shop has a head that the valves got loose in due to a busted belt on display. Figured you all might want to see
Here's what happens:

ouch
I have seen a pic posted a long time ago on TOB and it wasn't pretty. The piston and valves were in bad shape.
mitt
that makes me sad. :'(
Chomp
mmmm, chunky style
That might not buff out . . . ;)
This is what it's going to look like after i make my first attempt at porting and polishing [bang]

Good question!!!
Well if you're lucky, the engine manages to keep running and you pull off under control.
If you're not - the engine seizes and you poop yourself.
Loud noises which should prompt you to immediately pull in the clutch.

And pull out your wallet.
I had a head that looked like that. It wasn't from a broken belt; rather, mis-timed valves. I was on a test ride. I pulled in the clutch and coasted down a hill then pushed the bike home. At the time I was getting advice from V-2 in Australia. I called them up and then sent them the head. They filled the cuts and dents with weld and then shaped the head. 20K miles later and I am still using the same head. It did cost some $$ but not as bad as I feared. The big bore kit that I used to replace the trashed cylinder and piston was the most expensive part.

Yes, I've been able to turn every problem into an opportunity to gain a little more Hp and dependability.
