 +Ring Gap Positions during Installation:​
 +Exact ring gap orientation should be with the documentation that comes with a new set of rings. \\ 
 +The FSM's say to space the gaps an equidistant around piston. That leaves a lot of variance. \\ 
 +The rings will rotate during operation so they will not stay exactly where you put them. \\ 
 +This initial procedure for placing the ring gaps will help keep down blow-by during initial start-up while the engine breaks in the rings. \\
  
 +Orientation of the ring gaps is a debatable subject. \\ 
 +However the one thing most agree upon is the adjacent rings should not be spaced near each other.
 +
 +
 +|These are widely practiced ring gap locations during installation ((drawing by Hippysmack, gap locations by mikethebike61 of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​t=1572784&​page=2))|These gap positions are in the 2004 FSM via a drawing. ((04 Sportster FSM pg 3-56))((drawing by Hippysmack)). \\ However, specific rings notations are not (as they are below)|
