50mm Bore Cylinder Head Kit for GY6 50cc to 100cc Engine with 69mm Valves scooter taotao kazuma ATV Moped

I was on Amazon looking to purchase a bbk for my gy6 50cc scooter. I ran across this one here what cought my interest was the price $ for under $60.00 you cant beat it ??? I like the fact that the 4 dowel/locating pins come with the kit because most bbk don’t include them. In the photos I shared you will see a few other items that don’t come in this kit please be sure to read what’s included before purchasing !
