On my 2011, the petcock is has a setting for on and pri. If you turn it to pri, the petcock will bypass the vacuum and use the vent hose for air. You would do this to initially fill the bowls after draining them. In my case I have the carbs out to clean them because I let the bike sit too long. When I put the carbs back in I will fill the bowls using this method. After just a few seconds on pri (the fuel comes out pretty quick) switch to on. If the vacuum every failed, the carb has an overflow vent hose (the same air hose used when on pri) to vent the fuel out to the ground. I don’t see how it could end up in the crank case using this method. Also if you want to drain the tank (as in your are taking the tank off and you don’t want to manage the weight) remove the supply line from the carb and route the hose to a catch container. Switch the petcock to pri and out comes the fuel from the tank. If you open the gas cap and really let it breathe the fuel will come out pretty fast.

Hope this helps.
