    • The kids love it
Size: 125CC Engine Motor
Great little engine! Fast shipping! Got this as a replacement for one of the kids little off-brand atvs. Bolted right in. Sounds great! East to install. There was no instructions for the wiring harness so there was a little trial and error hooking it up but works great. Starter solenoid died after cranking it over less than 3 times trying to get it started for the first time but luckily I had the one off the old harness. Get a better air filter. The one in my kit was just foam and already ripped and crumpled. Oh and the shift lever is unusable in my application. I honestly don't know what it would actually work in. Lol Overall is it perfect? Nope. But I still have it 5 starts because, the shipping was really fast. Faster then expected by 3 days! Engine is nice. Sounds good. Direct bolt in replacement. Some of the accessories that came in the kit were a little chincy and unusable. Overall it's a great deal ... show more

    • Great product
Size: 125CC Engine Motor
The media could not be loaded. It came a little low on oil. Wiring took a little while to figure out. This was a special build so I didn’t have some of the safety relays that would be on an atv or cart. Engine started first crank sounds great and runs good out of the box. I used it for a winch motor on a trailer that will be hauling wood from 200 feet up a steep hill. ... show more

DO NOT buy this engine. I’ve probably only put about an hour total on the engine since I installed it, and the bottom end case cracked already and it doesn’t seem to be repairable. I didn’t have high hopes given the price point but I decided to go out on a limb, and unfortunately I wasted my money. It’s not worth it, spend a little more and get a higher quality engine or you’ll be buying another one soon. Would rate 0 stars if I could, hopefully my heartache saves the next person. ... show more

    • Not a bad replacement
Size: 125CC 4-Stroke Motor Kit
The clutch was sticky at first, until you get it going and shifting through th gears, then it’s works fine. Been having an issue with the kickstarter though, it goes into like a neutral for a few kicks, then gabs and fires rights up first kick (not grinding noise) Kind of weird.
