rocker arm assembly for GY6 50cc 139QMB/QMA BT13854
Complete rocker mechanism including shaft and valve adjuster for Chinese-built 4-stroke 139QMB/QMA 50cc cylinder heads. Changing the complete unit makes more sense than the individual parts, as damaged parts can affect other areas. Also saves time and effort.
