If your bike has a petcock, in addition to the vacuum valve, check to see if it has a "Prime" position.  This is used to let fuel flow freely, to fill the floats, as mentioned, when the bike has been sitting a long time.  Be sure to move the petcock back to normal, after starting, though, or you will experience overflow of fuel, as previously mentioned.  Cheers!
