Shawn and Araceli Harris –
The packaging sucked and it allowed the air filter to get crushed some but it bolted right up and works well so far. Has about an hour on it so far. Went on a small 4wheeler.

I pulled it out of the box n noticed a lil crack on the motor along with the pull start thought ok maybe a stress crack put fuel in it fired it up n then the crack broke off n the guard started to pop teeth maybe this one was a mistake but I ordered another to make sure if its cheaply made I’ll be back to tell you all

Awesome engine. Worked great on our xpro 50 bolt pit dirt bike. Had to adjust idle, as expected, and then great. Starts in 1-2 pulls .
