2--- Stroke Misunderstanding: Don't take 02 mode as 2 stroke, 03/04 mode as 4 stroke, this is a misunderstanding. If the 02 mode reads exactly 1000RPM, then it corresponds. The reason why we don't use 02 to correspond to a 2-stroke and 04 to correspond to a 4-stroke is because there are a lot of unconventional engines on the market itself, and you can't fix one mode to fit all engines.
