The starting of the motorcycle is mainly based on the pedal starting method. The starting mechanism has a sector gear starting mechanism represented by the XF250 motorcycle. The pedal start shift lever drives the sector gear, the starting ratchet, the sprocket of the clutch assembly, the front chain, and the crankshaft sprocket to drive the crankshaft to rotate and start the engine. After the engine is started, the starting mechanism is restored to its original position by the one-way action of the starting ratchet and the action of the return spring. This kind of starting mechanism, when starting, put the starting gear lever to the neutral position, and press the pedal to start.
The other is the starter lever type starting mechanism used by some imported models. Different from the former, when starting, the clutch handle should be squeezed first to disengage the clutch. The shift lever can be placed in any gear position, and it does not have to be placed in neutral. After starting, release the clutch and increase the accelerator to start. When the starter lever is pressed, the pawl on the starter lever shaft meshes with the inner ratchet of the starter lever transmission gear, so that the transmission gear rotates, and the crankshaft is driven to rotate through the idle gear, driven gear, clutch gear, and starter pinion. Start the engine. After starting, the foot leaves the starting pedal rod, the reset spring makes the pedal rod reversely rotate, the pawl is disengaged from the engagement with the inner ratchet, and the original position is restored.
Motorcycles with larger displacement, such as Changjiang brand 750D motorcycles, Yamaha two-cylinder motorcycles, Suzuki GT750 three-cylinder motorcycles, HON-DA CL1000 four-cylinder motorcycles, etc. Motor starts.
