Polished internals, what is so good about having it done?
thanks

polishing internals do what? make stuff smooth and shiny. less friction, faster cycle speed. when you polish the inside of your body, it slightly increases air flow, but not much.

if you do choose to do this be sure you dont leave deep scratchs, or sand or polish an part so much that you take away from the orignal size of the part, that could lead to leaks
