Thier "Predator" 4-cycle engines are cloned Hondas. I bought a 79cc to make a mini bike for my grandson for $99 and bought a 212cc 6.5 horse for myself. At the same price!
Took one out of the box and it looks real nice. Had to go look to confirm it was actually Chinese. Googled around and found folks hot rod the heck out of them. Take the governors off and run them at twice the RPMs. You can buy headers, high-ratio rocker arms, big carbs...seem to be good motors.
