So, it looks like Barrett figured it out.

So, what probably happened is that the bike is likely still running the factory stock (lean) map. Now with the Jardine, its going to run leaner. Add on that the fuel pressure was probably falling off as the leak in the hose got worse and worse. It was likely barely able to provide enough pressure to run the fuel injection making it run even leaner. At some point, things just melted down. In fact I think the wrist pins were starting to seize as well.
This also happened. So, they probably spun in the small end.
