RockyCMT, one thing you may not have noticed is stores like Advanced Auto Parts and Auto Zone typically separate the motorcycle/ATV and other oils from the auto oils. I spent 10 minutes going through ALL of the automative oils tonight looking tonight (I won't lie), only to realize around the corner was their smaller engine section which included Mobil 1 V-Twin 20W/50 full synthetic. Have a second look. 10$ per quart though.
