    • Engine worked great
Review Image by Jeannie Kapler Jeannie Kapler
I was very surprised at how good it ran and how good everything lined up and fit perfectly the carburetor that came with is no good but I used my old one and fired right up and has been running great make sure to change oil after running for a few hours and I couldn't believe it came filled with oil. Great little engine would definitely buy again if needed or want to go bigger. ... show more

    • Decent engine. BUT…
Review Image by Ian lynch Ian lynch
The media could not be loaded. Things runs good. But don’t expect name brand quality. When it got here, it was already full of oil. So was the box. When I went to put the carb on, I noticed a big nasty burr hanging on by a thread inside the carb. If you missed that you would probably blow up your brand new motor. It runs really hot too. Might shorten the life a bit. Also expect to get a smaller rear sprocket. I have the stock setup (42t) on mine and it tops out at 35 mph. It has plenty of power to haul an grown adult around though. ... show more

    • Wiring is not a plug and play
Review Image by Tim Tim
I had to splice the wires with the plug off the old engine. Paired with a 24mm intake/Nibbi carb./throttle assembly. Started on the first kick and runs great. 2013 Apollo 125cc. Factory 152fmi engine. This engine is 154fmi

    • Should come with more hardware
I was annoyed that I didn't get any hardware for the exhaust and this motor should come with an air filter. Other wise not to bad of a motor
