  • Muy buen producto
Excelente producto no pudo haber quedado mejor...

  • Great replacement
I had tried to put a big bore kit in my original motor and after having to rebuild the motor twice, I decided to give up. The original motor has too many problems trying to go back to stock. I bought this replacement and installed into my son's scooter. The motor is great and no problems. The stator plug was different from the original I had, but I spliced the old one on. The motor does not come with any emissions addons, so you won't lose the power. I added an 18mm carb withe cold air filter and straight baffled exhaust and this motor is moving right along. Started on the second try with electric start (first needed to prime the carburetor) After I got it running it started every time. I had a problem with the rectifier and I needed a new one, but the motor started every time I kick started it. Worth the extra money it cost than the other listing on Amazon. ... show more

  • It’s not worth the price
It doesn’t pick up speed like it’s supposed to and it doesn’t go 45 it barely goes 35mph
