Tried and tried and tried to get this to work and nothing but issues. Got it to run for maybe 30 minutes total but thats it. Even bought a new carburetor, exhaust, spark plug, chain tensioner, and magneto/coil and still couldnt get it to run. First big issue was the chain tensioner it came with. And even with a better tensioner, keeping the chain on the sprocket was a constant battle even though i made sure everything was aligned. The design of the carburetor is not very good either. All around nothing but a big headache. Would not recommend.

The kit comes with everything. The you’ll tools and hardware. In my case the frame of my bike didn’t really want to cooperate and I’ve had to do several modifications so the motor would fit. I had to take the chain guard off so the motor would come down as far as it could. I then manufactured a homemade spacer for the bottom of the motor mount out of the heel of a boot. Seems to be holding up fine.The next thing is the carburetor doesn’t seem to be wanting to stay securely in place. I’ve tightened it about as much as I can without feeling like something is going to brake. Still loose.Next the muffler can be modified by cutting the baffles out. Gives you a little more speed. I tried to take the nut loose off the bottom and it broke off. I think the hurdle can be crossed though. With a little modification.Lastly the sprocket that comes with this kit is difficult to install on coaster brake rims. I recommend putting the extra money into a hub adapter sprocket that has a hole big enough to allow for the brake arm. Or one that requires little grinding to fit. You’ll have to put it in a vise and bend the arm so it’ll clear the sprocket.Overall the kit seems pretty good. I like how it comes with all the tools; except for a drill. Good value for money. However, it does seem slightly cheaply made. You can definitely tell these are mass produced and the customer (you) is quality control.Some pieces of valuable knowledge I’ve gained from building a few of these….Use thread locker on exhaust bolts! Really, use thread locker anywhere you can, because as you ride things loosen especially during brake in period. Keep a few wrenches handy as you ride. Before you go ride, check your bike. Make sure nothing is loose. Check tire pressure and wear a helmet. Going through a few check points will help you have a better ride experience.Always check for loose parts. always check for loose parts. Always check for loose parts.

The kit was very fast getting up to around 30-35mph. Definitely need more experience than suggested to put this together well. I rode it for maybe a mile and a half and I noticed that the muffler was loose. Trying to screw it back in, it broke right off getting stuck inside the cylinder. Had to get help from a friend that spent around 2 hours to install a new part just to get home. Not even 30 minutes of riding and it broke. Very disappointed, asking for a refund.

THIS KIT ISN'T PLUG AND PLAY!!! there is things you'll have to trouble shoot and fix, it isn't as simple as putting it on the bike. the kit comes packaged well with the gas tank and motor in a Styrofoam box. all peices in the kit are quality, comes with a 4 bolt tensioner unlike what is shown in the photos. when you get the motor, align the magneto, grease the drive splines and make sure the piston is orientated in the right direction. the kit took me 3 hours to assemble with minor modification. my kill switch had a bridge between the contacts so check that to make sure thats not your problem if your not getting spark. when installed properly and set up it runs good! break it in on 20 to 1 conventional then run it on 32 to 1 full or semi synthetic for the rest of its life. Id recommend upgrading the exhaust and the spark plug as you start as with getting a 36 tooth chaining. dont buy this kit if your not mechanically inclined, it doesn't just bolt together. great deal for 140$

This engine performs really good. Ranging from speed, fuel efficiency and reliability. Topping out at around 30-35 mph for me. I get around almost 50 miles per tank which isn’t bad at all for such a small engine. It’s a reliable engine as parts are cheap or expensive to fix but it differs. Ranging from 10-100 dollars per part/set.A couple down side parts about this engine is how it maintains. I’ve had this engine for about a month and it was slowly dying on me until it gave up. Parts from inside the engine and outside were breaking off. While also destroying the inside of the engine. Parts are cheap but with all of the money I spent on parts. I could have gotten me a brand new engine kit/set.Now these are Chinese motors and I wasn’t expending alot from it. But surviving only a month and it broke on me already? That’s pretty bad. I’m giving this product a 3/5. A three for the fuel efficiency, speed and reliability. Removing two stars because of how cheap the engine is made of, and how easy parts can break off. Also because of the engine dying on me.This is my honest review. Thank you for reading. I hope this helps you understand this product and thinks about buying this.

There are numerous problems with the kit itself. Off the top of my head: the carbeurtor has a fuel leak right out of the package. The wires don't fit into the connectors. The chain it comes with is terrible. The sprocket it comes with is made of cheap material. The two pieces of rubber that are for the sprocket are terrible. The instructions are vague and blatantly wrong sometimes. The spark plug doesn't spark. This is not worth it's price. The engine blatantly doesn't work. Save your money and just buy an ebike/motorcycle/minibike with less building requried.
