Shipped very quick and runs well I'm pretty happy with it. Don't forget to hook up the brake safety switch or it won't start. Seller was very responsive thanks.

I made a mistake on not checking everything when arrived, by the time that I checked and installed I realized that the wire harness wasn’t the right one for the engine, I contacted two electrician on motorcycles and they agreed with me to, I haven’t been able to start the engine because of the harness and besides that there was no instructions at all it was a video on line with out volume.

Just installed this 125cc engine on my go-kart, and so far, it’s running pretty well. The power is solid—definitely an upgrade from my old motor. The 3-speed gearbox with reverse is super handy, and the electric start works without any hiccups. Wiring was a bit confusing at first, but the color-coded harness helped sort things out. The build feels sturdy, no weird noises or vibrations, and it bolted right into place (double-check your model first, though). Only minor gripe is the instructions could be clearer, but if you’re familiar with small engines, it’s manageable. Seller was responsive when I had a question, which is a plus. For the price, it’s a decent deal if you need a reliable replacement or upgrade. Just make sure you’re comfortable with the install or have a pro handle it.

Would not recommend buying this engine don't waste your hard earned money on it. Got one sent out came in pretty quick but couldn't not get running had spark and gas and air simple should start nope customers service was nice enough to send a second engine got running same day but always had clutch problems either was engaging all the way or at all even bought a different cable length to help nothing worked. Ending up getting to a point and it was fun till 🙃 the transmission let go of 3rd gear no matter the adjustment or cable u have that clutch will not full engage for a smooth change of gears and no information available to help you fix the problem spend ur money some place else do more research than I did

Never could get it to run correctly. Would start and die. Tried tuning carb, adjusting everything i could. It fit on the mini bike fine, but the wiring harness would smoke when hooked up to battery. Wouldnt buy again.
