[QUOTE=RPinoski1;117276].043 With no lateral gas ports. Lateral ports create a vacuum leak on the intake stroke so now not the way to go anymore.
Napier second ring with twice the end gap as the top ring. Eliminates top ring flutter.
Remember: This type of ring as with all secong rings is for oil control only hence the larger end gap.

Vacuum leak on the intake stroke, not so... look at the top ring after run and you will see wear mark on the bottom inside whare it seals on the intake stroke... also second ring, especially napier not only controls oil but its reverse taper face aids the intake charge...
