This engine is excellent and easy to install, I put it on my XR50 motorcycle and it started up with just a few pulls and was easy to use, it runs great and is fast. And this engine comes with a 4-speed manual clutch transmission, a shift pattern that I love, it's a great product and I'm very happy with it.
