Is the motorcycle throttle a throttle?

No, motorcycle throttle and throttle are both parts of carburetor, and they have different functions. The function of the air door is that after the air door is opened, the carburetor will provide the engine with much larger fuel supply and much thicker combustible mixture, so as to facilitate the motorcycle to start easily in cold weather. After closing the throttle, the fuel supply and mixture of carburetor will return to normal. The function of throttle is to control the amount of air entering carburetor to control the size of motorcycle throttle.
