idle shaft gear / kickstart pinion gear - 8 splines for GY6 50cc 139QMB/QMA BT24486

Kick-start sprocket with very strong teeth to deal with heavy loads, as they transfer the power from the kick-start to the crank. Many starting issues can be traced to the kick-start. 2 different versions with either 7 or 8 teeth are currently used. This version is the 8-tooth version. Please check product image and compare to original part.
