Review: Good upgrade from a 107cc - Runs like a champ but wiring sucked
Review: The kids love it - 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

### ⭐⭐⭐⭐ Runs like a champ!
*by M***0 on December 4, 2025*

This rating should be lower but the actual engine runs great, fit well and the price is incredible! Reason I would have rated lower is the CDI it came with did not work, luckily the old one did. The pipe from cylinder to carb had a hole casted in it rendering it useless, again, the old one worked. This could be good or bad but since I hate wiring, it was bad to me... It comes with at least twice as many wires as I needed. Again, this could be a positive for some.
