My 916 went dead on the highway. Later I thought it was a disconnected fuel line in the tank. I fixed that but noticed something really weird, gas dripping from the lower exhaust pipe when I try and start it. Eventually the bike wouldn't turn over and the site glass showed no level of oil, it was like I put 8 quarts in it. I suspected that fuel was getting into the motor somehow and confirmed that when I opened the drain plug. An ugly mix of gas and oil and lots of it came out. Since I thought it might have been that fuel line, I put fresh oil in the bike with a new oil filter and tried to start it up. Again, gas was dripping from both lower exhaust pipes so I immediately shut the engine down. This time the bike turned over due to the fact the engine wasn't filled with gas. I disconnected the fuel lines and connector and hit the starter switch and the bike actually started. It went with what fuel was in the lines which was for 4 or 5 seconds, but I still noticed gas dripping from the seams of the lower exhaust pipes. Both pipes. I removed the horizontal exhaust pipe and you guessed it, it was full of gas! I suspect the vertical cylinder is full too because it was dripping gas as well. BTW, no signs of gas trail back to the connectors or the tank that I could detect.

What the hell is going on? I can only guess a throttle body or injector is gushing gas into the cylinders. But both cylinders, or is it one and it just overflows into the other?

Has anyone had this oddball situation? I just ruined 8 fresh quarts of synthetic and two oil filters.
