I got a question; does radically hypertuning a Honda HRC 216 do anything bad to it? Reason I ask is one of my crews learned that if they just tweaked some springs or something up near the engine, the engine would go radically faster. So they did it to two of our mowers. Now the blade moves faster, it drives way faster, and it's twice as loud. I don't mind. They were able to mow the big lawns in almost half the time today and the lawns looked as good as they always do. So I am inclined to let them keep them this way. But I want to make sure it's not going to do any damage at this higher rpms.
