  • Arrived quickly and in great condition. Great seller!
My Grandson was so happy to receive this for his birthday. It arrived extremely quickly. He had it all put together in just a couple of hours and it works perfectly.

  • Clutch Arrived Broken
With little modification, this engine & kit was able to fit on a 19" Frame Specialized Hard Rock. Runs well, but the clutch never worked out of box. I fixed the clutch with an Oilite Bushing as the default bushing was the problem not the clutch itself.
