  • Top end assembly

    Posted by Daniel Barajas on Jun 14th 2022

    Everything is good it runs good and all. Only thing is I paid the extra $30 for the top end assembly and one of the ignition wires were bolted down inside of the actual cylinder scoring it up. It probably took some life of her for sure but it’s ok

    I ordered the silver slant 66/80cc kit because it was on sale. I paid the extra $30 for the top end assembly, and one of the wires for the spark was bolted down inside the cylinder and it would’ve destroyed itself if I tried to turn it over at all. There was tiny pieces of copper and metal from the end of the wire all inside the crankcase and cylinder. Other than that it runs great so far. Just do it yourself lol

  • Great starter kit

    I bought this motor about a month ago as my first kit. Honestly it has been very reliable, starts up every time with not extra fluff. I&#039;m giving 4 stars just because it has a decent amount of vibration when going full speed, but isn&#039;t to bad in the lower RPM. I haven&#039;t tuned the carb yet, but I am able to go 27 MPH and I weigh about 250 lbs. Overall happy with the purchase!
