Review Image by John Ray Clark John Ray Clark
Works very well on pitbike that I have, pretty powerful for a 4 stroke 125, I recently got the pit bike from a niebor who was just going to throw it away, the original engine I pulled out of it needs a top end, I wanted to start with a fresh engine. It is very responsive, these engines can be used in multiple applications as well, I have personal seen them on bicycles,quads,scooters/mopeds. They have multiple uses, I am very impressed with these little engines. I have used these in the past on multiple projects, when set up correctly,they are pretty reliable. ... show more

Carburetor sucks. Good motor carburetor no good.
Reviewed in the United States on November 14, 2023 by It’s really hard to get started at first. Carburetor that if come with is trash. But once you get it to go very impressive.
    • So far so good! Change the oil!
Color: 140CC 4-Stroke
The media could not be loaded. So far so good. Had to figure the wiring out but was simple. 2004 XR70 swap to 140cc Drained the oil after warm up looked a bit thin still oil but very thin. Swapped it out with some 10w/40 much smoother. Everything was cringy untill new oil was used and ran another warm up. I'll change it again after I run it a bit longer. So far happy with it. Starts and runs good. Gears feel good going in and out but make sure your shifts are solid ... show more

    • Faulty transmission
Color: 125CC 4-Stroke
After installing this motor and properly breaking it in, the bike continues to go into neutral on its own. I am a seasoned rider and have never had this happen before. My nephew rode the bike and the same thing happened to him. You can get seriously hurt if you don’t know what you’re doing and your bike goes into neutral mid ride. I wouldn’t want anyone else getting hurt. ... show more
