## Customer Reviews

### ⭐ Do not buy this engine kit
*by D***N on February 2, 2025*

The clutch is garbage. The engine can only go speeds of 25mph. And after two weeks the clutch broke. And you can not find a replacement clutch for this engine. Do to the engine shaft size being thicker then every other 49cc engine kit ever.and the key way being bigger to12mm to 14mm shaft size is standerd. This brand DOES NOT USE THIS. If you buy this every time the clutch goes out you'll have to buy a new clutch and take it to a machine shop. With all that being said the engine does run

### ⭐⭐⭐⭐ Strong engine
*by D***E on August 28, 2024*

It's a torquie engine just make sure you locktite all the bolts. And don't over tighten the bottom engine mount bolts, one of mine broke off. I hit a bump and the transmission casing came off not to long after the flywheel went flying down the road, ride safe and enjoy! Anyone know where to get replacement parts much appreciated!?

### ⭐⭐⭐⭐⭐ Great product
*by L***A on August 20, 2024*
