In general, a pull start, also known as a recoil starter, is a mechanism used to manually start engines, including those found on motorcycles. The purpose of a pull start on a motorcycle is to initiate the engine's combustion process by manually turning the crankshaft.
Here's how it works: When you pull the starter handle or cord, it rotates a small drum or spool inside the starter housing. This drum is connected to a coiled spring, which stores potential energy when it is pulled. As you release the cord, the spring rapidly unwinds, spinning the drum and transferring the rotational force to the engine's crankshaft. This rotation initiates the engine's firing sequence and helps the motorcycle's engine start running.
If a pull start is not used or not functioning properly on a motorcycle, it means you won't be able to start the engine manually using that particular mechanism. In such cases, you may need to rely on alternative starting methods, such as using an electric starter (if available) or addressing the underlying issue preventing the pull start from working. It's worth noting that some motorcycles may not have a pull start mechanism at all, relying solely on an electric starter system.
