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

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.

Kids love being able to ride their bike again! Came as it was described good quality at a great price. Super easy install!

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.

Runs ok but every time I ride it another gasket begins to leak I’ve already made all new gaskets for the head and now it’s leaking between the cylinder and the block and even leaking out of the split in the block and transmission and then looked today and it’s leaking out of the shifter O ring

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.

Good for the money

Great engine but what size chain does it take
