  • awesome product

super fast shipping an overall great item very happy with my purchase

  • Bolt holes
Size: 49CC 2-Stroke Motorcycle Engine Motor Kit
For the most part this works great. Good power, not too loud, starts first pull, easy install, but one of the holes on bottom of motor won't align with holes on bike frame. Maybe a drill and a large washer will fix, but 3 bolts holds the 49cc in place.
