## Customer Reviews

### ⭐⭐⭐⭐⭐ The kids love it
*by L***A on March 20, 2025*

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. LolOverall 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

### ⭐⭐⭐⭐⭐ The quality of customer service is outstanding
*by L***T on May 17, 2025*

Fantastic engine and customer service the engine showed up early and was in perfect condition besides one cable that got pinched and cut but I messaged them and they refunded me some money to purchase a new one. Can't complain with that, thank you much!And for anyone wondering how to wire the engine I've attached a picture from the Internet on how it's done.

### ⭐⭐⭐⭐ 3rd motor I’ve purchased!
*by S***J on July 2, 2025*

Just opened my 3rd engine from them and there is motor oil on outside. The first 2 are still doing good haven’t had issues feels a little slower but probably need to be fully broken in!! Sure it happened during the shipping the foam was cracked pretty bad so hopefully it wasn’t dropped or rolled over. Kind of scared this one was damaged in the shipping process will do update after test!
