Question for the motor heads. I?m looking at a second run IO360-A1B6D for my RV7. This configuration has the single drive dual mag configuration. Although certified, I?m always a bit leery of single point failure opportunities. Does anyone have experience converting a A1B6D back to a A1B6? I know it requires a different accessory case, gears, etc. I guess another option would be to go with dual electronic ignition, and just cap the mount pad. Any thoughts?
