Great Value and quality as described
If you're new to engines in general, you'll find that the wiring is not intuitive. Once I figured it out, it worked great with my 125cc Chinese pit bike engine. The key works well too. The extra spark plug is a plus. If someone else doesn't know how to wire this, I can offer help, since I found very few resources online.
Excelente todo funcionó bien en el ATV exepto la shichera salió humo luego de conectarla.
Fits quite well with some zip ties. But the switch doesnt work so I had to splice a kill switch in.
