In browsing through other threads I commonly read people talking about their 2 stroke acting as a 4 stroke while cruising and 2 stroke when accelerating. Ok...what does this mean? If it's a 2 stroke, how does this thing 4 stroke? The SLIGHTEST Idea I can come up with is that this pertains to a different in pitch from the engine because It sounds more of a pop pop pop when cruising but more of a brrrrrrrrrr when accelerating, but I can be way off. Any insight?
