I found another way, if you want, and it involves using the vacuum feature on the petc0ck...
Since the fuel is vacuum controlled with the petc0ck set to the On or Res position, put the lever in one of those positions, and start the bike. Then with the bike running, pull the vacuum line from the carb on the right side. The idle speed might change a little, and you might want to use the choke...but with the hose off, the engine will run untill all the gas is sucked out of the fuel line and the carb bowl.
Pretty simple. Just don't lose that little hose clip.
