## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome 100cc bbk
*by K***N on April 4, 2022*

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 !

I like this kit.Comes with everything you need to replace your top end. Obviously not the cam or cam tower or slides. But I knew this and everything fit great and had no issues. 5 Stars from me
