I am rebuilding a Force 70 HP with a set of .040 over Wiseco pistons. After boring what method should I use to set the ring gap. The manual says .010 - .020 for the top ring and .006 - .016 for the bottom ring. This seemed a little on the side of alot of tolerance. The general method Wiseco suggest is .004 x inches in bore for the bottom and .005 x inches of bore for the top. That figured to be .014" and .017". This looks to be more inline to me. Not that I know anything about 2 strokes I'm more of a small block chevy builder. The bore is 3.514" if that helps. Thanks for any information or suggestions.
