  • Great solution
Size: 125CC 4 Stroke (Horizontal Engine)
Replaced the motor on the kids coolster. This is a three speed, I didn’t realize that when I bought it. Not really a big deal. Good to teach the kids how to shift. Literally bolts right in. Had to cut and splice the main wire harness for the quad, not a big deal. Headlights aren’t working so I’ll need to look into that. Really happy with it. Had the quad back running in less than 2 hours. Talk about something right out of China. lol the engine came in a smaller box wrapped in a trash bag 😅. Everything works! ... show more

  • Support is helpful to a point.
Size: 125CC 4 Stroke Semi Auto
Major problem for me was getting a difinitive answer as to which of the two yellow wires coming out of stator was supposed to plug into the white wire for charging the battery. They sent me charts and diagrams of a white to white wire connection which didnt exist in my harness. I was afraid to damage the stator and face a possible refusal of refund process. Tired of waiting for an answer, now total of 3wks, i spun up flywheel with cover removed with a drill motor and found voltage output on one yellow wires which i plugged into battery white wire with battery installed. Feârful of damage, and no answer, I had to solve my own problem. Engine starts, runs and charges fine. Will change Questionable oil as its clear like mineral oil and no data what oil other than mineral it could be. Suggest first run with tappet cover removed to verify oil pressure to head. Another strange fact is the four threaded holes on bottom of crankcase for peg support bracket is threaded with M8x1.0 and nobody local or even Amazon doesn't have one of that bolt just the M8x1.25. Its like banished from the earth. But you can get the tap or die. Lol. ... show more

  • Great motor for the price
Size: 125CC 4 Stroke Semi Auto
I bought this for a homemade drift trike, as seen in the pictures and I cannot be happier. The thing rips around. My sprocket ratio on the trike is 1 : 2.14 or (14 tooth front , 30 rear). When searching for parts that will work with this motor. Be sure to look for "chineese 125cc" or "Tao tao" wich is identical to this motor. The only issues have been the fact that there is no literature in the box and the only information that can be found regarding the motor is on this Amazon listing. So if you order thinking you will have instructions in the box, your mistaken. ... show more

  • Runs great
Size: 125CC 4 Stroke (Horizontal Engine)
Got about 20 hours so far and after carb tuning and shift indicator rewiring, it's awesome. Motor was covered with oil from box being flipped around in shipping. But, it runs perfect and shifts great. Smoked a little on first start from oil in the cylinder but cleared up in about 5 minutes of running. This is mounted on my kids' khandi 125 gokart. Also changed engine oil immediately with 20w50 synthetic. Would highly recommend for your kids gas powered toys. ... show more

  • It’s okay
Size: 125CC 4 Stroke
The media could not be loaded. When I got it in January the timing chain was 3 teeth off and after I fix it I had to bet the hell out of it to run why idk but it’s perfect now no problems.
