Complete rocker arm bridge including shafts and valve adjusters for cylinder heads (suitable for item no.: BT13851) for Chinese 4-stroke engines 139QMB/QMA 50cc.
Replacing the complete bridge makes much more sense than repairing it from individual parts. In most cases, more components are affected by a defect than first meets the eye. It also significantly reduces the assembly work.
