You can do various saw mods that won’t hurt but can help reliability and gain power,but when you make the port openings bigger in the cylinder,then piston and cylinder wear can occur,depending on how the ports are reshaped,there is no way around it,much bigger holes in the cylinder will cause more cylinder and piston wear,however if port mods are carefully done and don’t go too big,premature wear may not be significant. That will increase power and not affect wear at normal rpms,an example is a free-flowing muffler will make more power and evacuate heat faster making the piston run cooler and help engine life. So carefully done mods can create more power in the normal rpm range and not adversely affect engine life.
