    • Inspect before install

Inspect parts and engine before installing. my gas tank arrived rusted inside, but I fixed it with vinegar. The clutch cover came with a gash on bottom that I filled in with gasket maker. The engine had some small dust and bits of metal inside so I removed jug and cleaned it also grinded off the casting on intake and exhaust ports with a rotary. I ordered 100cc silver. Idk if it’s actually 100cc. As the engine just has a picture of a parrot where the displacement should be marked haha. starting it first time took a long time with long stretches of hills, but it’s doing good now, very fun to ride literally anywhere. all controls work. Starts easy now, had to do some idle adjustment on the carb, I hate the chain cover. ... show more

Style: Silver 100cc
I couldn't believe how much prep work is required before I can mount this motor.. I have to buy all new gaskets because they used gasket maker on everything you need to take apart and the intake and exhaust ports are not lined up with the sleeve I had to do a lot of port work to correct it.. the head , piston and even the crank were gritty.. I can't even use this motor until I get all new gaskets.. worst build quality I have ever seen.. if you never worked on motors like this don't buy it look for a more reputable company to buy from.. I've been a mechanic for about 30 years and I've never seen a brand new motor this bad ... show more

    • INFERIOR QUALITY… 75% of the value in shipping costs to return… BEWARE!!!

Extremely poor quality … sand casting overruns not even pretending to clean up ALSO ARRIVED WITH BROKEN PISTON RING… piece of it was visible through spark plug hole… took it apart to repair because YOU CANNOT RETURN IT!!! Buyer Beware this is garbage and unless you plan on rebuilding this completely as well as buying better parts to go back on it YOU ARE BETTER OFF BUYING A USED ENGINE…same exact deal only way cheaper… and shipping costs to return is ridiculous!!! $92 for me to return to their warehouse in CA… unless you live there the the return probably be to New Jersey… PLEASE DON’T THROW YOUR MONEY AWAY LIKE I DID… AND I HIGHLY RECOMMEND IF YOU ARE NEW TO THIS TAKE MY ADVICE… buy a used complete bike setup on marketplace from someone who built one and have a long discussion about what products they use ... show more

Awesome engine. Install was straight forward. Runs strong 💪. Though though I believe mechanical knowledge tools and ability are required I had no problem with it and for the money how can you go wrong
