Thanks. If you're willing, I'd like to know more of the specs between the two pistons/rings. To determine if a simple "ring delete" is a valid modification to a non-XFi engine.

I realize it would be a lot of work for a tiny gain, even if it could be safely done (safely in terms of the wear/mechanical implications to the motor). Just noodling.
