## Customer Reviews

### ⭐⭐⭐⭐⭐ It works very well and has very good compression and easy to install.
*by J***E on April 22, 2021*

The media could not be loaded. It works very well The engine was very good and apart I did my job It has good pressure was exactly what I asked for and what I wanted the only thing that they do not put the kick to turn it on is an observation they would have to put the kick to turn it on But in the description said

### ⭐⭐⭐⭐⭐ Replaced Redcat 110cc ATV engine with this
*by J***R on April 13, 2022*

My son's Redcat ATV had a working 110cc engine, but was very difficult to shift and chain kept coming off. Replaced with this 125cc engine. Electrical connectors were not the same, but once I figured that out, engine works great!

### ⭐ Trash engines!!
*by R***. on February 28, 2023*

These engines are trash, 2nd and 3rd gear was non existent on first start up. Starter was also faulty and had to use the old one from the original engine. Seller tried to not refund, saying the wiring was cut from the stator. Anyone who knows anything about these engines knows they come with no plug on the wires and have to be hard wired to fit the existing wiring harness. Sellers practices are deceitful and their engines are essentially JUNK! Keep looking, better products and sellers who have more honest selling practices out there.
