I have an 04 919 that's been giving me a hard time as of recent. It's pretty hit and miss when it does happen, but here are the symptoms.
I'll be riding along with a full tank of gas and then my gas light will come on. Within a minute or two all my gauges will die, and then the bike will die. I'll turn it off and then back on and my battery will be almost completely drained. Or at least too drained to start the bike. It will start off of a bump start however.
I brought it into a local dealer and they checked the battery, and it was good. The also told me the stator was fine as well. I left it with them for a few days so they could see if they could replicate the problem, but they couldn't.
Anyone have any ideas? I was just going to keep driving it and bump start it when I have to. At least until the problem is more frequent, and then have the dealer check on it again.
