    • Pretty good.
Color: Black Size: 50cc
The media could not be loaded. The engine runs more smoothly than I thought. You need to lift the choke on the carb for a few strokes during startup, just in case anyone doesn’t know. The main concern for me is the chain tensioner. It’s hard to tighten, and it’ll be horrible if it gets into the rear wheel. For my bike, the plastic wheel on the tensioner isn’t aligned with the chain, so i spent quite some time to get it right. Every time you start the engine you essentially give a pull on the tensioner. Better keep it in place. The exhaust pipe gets into the way of the pedals, so had to mount it the other way. Wasn’t able to seal it so it’s crazy loud right now. Engine mount was quite universal. However i was only able to mount on one spot. Works out fine for me. ... show more

    • Junk don’t buy
Color: Black Size: 80cc
Terrible I ordered 4 engines from them and they all came late but they also all were abd and had bad clutches or heads never had a problem like this with any other engine. They also wouldn’t send me a refund and now I have to go out of my way to get labels printed and pay to ship them back.

    • Good for learning
Color: Silver Size: 80cc
Honestly, with how cheap the price was, I wasn't really expecting much from this engine set. The installation is pretty straight forward, if you know what your doing or have a talent for working on engines. An installation guide would have been nice anyway. I was able to get mine up and running in about an hour and a half. All parts were about the quality you would expect it to be (ie. not that good). I bought mine on the 9th of december 2023, the engine locked up on me on the 22nd. That's less than 2 weeks. ... show more

    • Its okay but this is what i observed
Color: Silver Size: 80cc
This was an okay kit, it does have it's fare share of problems. From what I have seen it is mostly athetect. However it does have a few mechanical flaws. One of the biggest annoyances is the owners manual, it seems to have been written by someone who doesn't have complete in place about how to put the kit together, as well as not knowing how to write an owners manual. As far as I have noticed asthetically the fins on the cylinder head are cheaply made, because it tools like they were cuz with an angle grinder, their is also the paint issue, on the fuel tank. It looks like it was done haft asked, because I can see bubbles and it being slightly uneven in some areas. One final problem area that I encountered was the sprocket that gets installed on the rear rim was surprising crooked so I'm going to have to order another one of those, although I have already planned on doing that from the get go, so it only slightly bothers me. The building posses is actually verry simple, mostly straight forward, the manual does a mediocre job at best to help with the build posses, With all that being said this is a great project to do for someone who is wanting to have a small fun project to have with a younger family memeber, I do not expect it to last long in my hands and that only do to that fact that I'm allways extremely hard on these small cheap engines. ... show more

    • This is garbage
Color: Black Size: 50cc
The instructions are unclear and don't even tell you how to put it together properly and don't even mention half the parts that came with it. It also doesn't even fit in the frame of the bike even though I got the size that it's supposed to fit in. The engine fits but not with the carburetor connected. I've been working on this bike for 2 days and have basically got Noware bc I have had to redo everything 3 times bc the instructions don't explain how to put it together properly it just says connect this or that look at pictures but the pictures are small blurry and Incomprehensible. I was very excited to get this but every hour I spent working on it getting noware makes me regret this purchase all the more. Hope this helps ... show more
