Good engine
Had some issue with the motor kickstart. But they kindly replacing it. But other wise very solid engine perfect for small pit bikes.

No instructions
The product itself is a good running engine. No instructions came with it. There is a pinned connector exiting the engine case that fits the cdi and what not. This connector goes to the transmission for a gear indicator and will not facilitate a running engine. It took me a little while to figure that out but once I did I slapped this bad boy into a 1984 honda TRX with a very minor amount of modification to the fame(drilled one 1/2" hole).

Terrible motor Terrible motor
A transmission bearing blew in less than 5 hours resulting in a hole in the side of the motor, seller refused to warranty the motor and treated me like an idiot saying that it just needs a new bearing and the hole would not hinder performance not to mention the chewed up transmission gears and shafts. After I proved him wrong with photo and video evidence, he stopped responding to my emails. The motor came damaged right out of the box, I provided a picture of the top tappet cover. Save yourself the trouble and order from a more reputable company like tbolt usa or bbr proformance. You could consider that maybe I got the only dud in over 1,000 motors but the customer service speaks loudly. I wish there was a zero star option for this rating.

Replaced a dead pitbike engine on a TaoTao DB14
This engine has been solid for 2 years of some pretty hard riding by my son and various adults. I replaced a faulty engine on a TaoTao DB14 and have very few complaints. I used another carb that I got here for $15, usually starts in 2-3 kicks and runs very strong. The shifter is a little clunky for kids and the case is wider that stock but I expected that. It bolted right in, I also had to get a new throttle cable because of length. Change the oil immediately, use 4 stroke motorcycle oil.
