Becouse the piston, rings, and cylinder wear out and you start losing compression. Depending on how weak your top end is, tells you what to do. I redo mine when the compression drops to low. When mine wears out I Bore the cylinder and replace the piston and rings. I am not familiar with 4-strokes but I am sure you need do something with the valves in the head also..
