I turn the petcock off as I pull into my driveway - I leave the bike running while I park it in front of the garage, dismount, open the garage door, and roll it back into the garage and turn it off. They important thing is to get into a routine and stick with it.
Of course, while at the MOA rally in Tennesse I Started out one morning (before I had my coffee mind you) and stalled before I got out of the fairgrounds - forgot to turn the petcock back ON!
