My AQAD 41A has six badly scorn liners since it was rebuilt 2000-hrs ago. One moderate overheat in past 5-yrs. Curious what possible outcome would occur if "A" series pistons are replaced with "B" series pistons and WITHOUT making all the other necessary upgrades and modifications. I realize there's much more to converting a 41A into a true 41B but I need to confirm if replacing the pistons ALONE could cause scorn liners and perhaps other premature engine wear within the 2000-hrs.
