When your 4-stroke motorized bicycle’s engine will start, the transmission chain’s in tact, but your bike won’t move, it’s time to replace your Transmission’s Output Shaft. Made of high-grade metal for the strongest drive sprocket shaft possible, this Transmission Output Shaft will assure your transmission pulls your motorized bike properly.
The 4-Stroke Output Shaft is the shaft that connects the drive sprocket to the transmission of 49cc 4-strokes like the Flying Horse 5G and Huasheng 142F 4-stroke 49cc bike engine kit transmission. Just open the case; remove the drive sprocket, freewheel, and transmission chain; remove and replace the output shaft; reinstall the transmission components, and you’re ready to ride!
