YUEWO 80cc Motorized 2-Stroke Upgrade Bike Conversion Kit, DIY Petrol Gas Engine Bicycle Motor Kit Set with Speedometer for 24", 26" and 28" Bikes (Sliver)

Total lack of instruction on anything.No guide on how to put carburetor together.No information on wiring the coil.

The engine runs but nothing like my other 3 bikes. Did a compression test and the engine would leak down rather quickly. Fuel is leaking out of the carb because it has a bad float valve and the throttle cable is way too long. Top speed on gps is only 17mph which is 7mph slower then my other stock engines probably due to the compression issue.

Well the motor was good but when I got put the gas tank on the gas tank was leaking gas as y'all can see I did a video I mean they sent me a bad gas tank now I can't ride the motor on the bike now I got trying to purchase a letter gas tank which is that's a ridiculous I paid $159 for damn motor not just got the motor on the bike damn gas tank leaking

Has no instructions not hard to figure out but never want to run right and also did not come with both set of spacers for sprocket like most others do

This is no different then a basic chinese one that you would by on Aliexpress or Banggood. The clutch is such poor quality that it locks up. The tank leaks, And theres no instructions. DO NOT BUY THESE CHINESE ENGINES. They only mark them up when in reality they cost only $90s or so on these sites. Dont be tricked by the name either. Not a real name. Just a gimic to sell them. I have disputed it since this is not returnable due to it being a fuel based item.

I installed the engine on a 24” bike after altering the frame of the bike. The engine ran fine. My main objection to this article is that the instructions are not well done at all for English speakers. I am fairly knowledgeable about engines so I managed, but it was not because of the instructions .

I put it on an old Huffy. Great detail and Great for the price.

Fastest, and earliest delivery ive ever had, contents are perfect condition and marked fragile. Excelent value.

The kit came with everything, not too hard to install and it’s quiet, equivalent to neighbour cutting grass with a trimmer
