  • Works great!
Easy install, works great! It doesn't fit on a GK110 TAOTAO but I already knew that. Once I got it mounted it started right away and was very easy to install. Make sure you purchase a carb

  • Cracked engine! No support!
Should be zero. Engine has a crack in it when I open the box! And now it seems I have to pay to ship it back!

  • Engine swap on a kc110 from 110cc to 125cc
The media could not be loaded. Good for learning to ride a pit bike , the automatic drive with no clutch needed helps my son focus on balancing for training

Wiring came with different connectors, (easy trip down to hardware store to solve that problem)and the reverse and forward where opposite of the original motor. But other than that I got it installed and it started right up
