### ⭐⭐⭐ 







  
  
    Great engine, lousy customer service
  

*by B***D on Reviewed in the United States on October 5, 2022*

Ok, first off, beware that you must be savy with thinking outside the box and being adaptive when undertaking this attempt to modify a bike. This project is not for beginners. All bikes are different and newer bikes are not standard at all and may not accept this engine to the frame. Be aware there are NO INSTRUCTIONS included with this engine. YouTube is your best help, but even that is limited. Now, the engine works great and starts with one pull. I was super pleased with it. However I did not receive all my parts with the order. I was missing the throttle and engine cut off switch. After a month of the company telling me twice that the part was being sent, which never arrived either time I was told, Amazon helped me file an A-Z claim to make it right. So my recommendation is that the product is fabulous, but heaven help you if it's missing a part as customer service is non-existent.

    Missing pieces
  

*by A***R on Reviewed in the United States on September 2, 2022*

Haven’t checked if the engine works as the manual indicates that it should be mounted prior to starting.Looking over the engine I see no reason it won’t work (amateur mechanic); it seems fine- edges need a lil bit filing, bots need some torque, oil and gas.

### ⭐⭐⭐⭐ 







  
  
    Great motor!
  

*by J***L on Reviewed in the United States on April 21, 2020*

Motor runs strong and starts in 1-3 pulls every time. But I have to knock a star off for a few issues:Do yourself a favor and buy new fasteners! The ones provided are junk.Also do some searches in YouTube for good install instructions! None are provided by the seller
