Hi fiude
Yes, This Forum is located in the United States of America. Meaning; I am in the USA & so is the forum.
Lifan didn't import a 125cc motorcycle to the USA. They {Lifan} imported these bikes, LF 150GY, LF 150GY-3, LF 200GY-2 & LF 200GY-5.
I'm not sure what wiring the Lifan 125 engine you have has, {It could be an OHC = Over Head Cam or a Push-Rod engine} or what wiring harness the Samurai bike you are putting the engine in has. It would depend on what manufacturer who made the original engine that was in the Samurai bike how the new engine will be wired. You may even need to change the CDI box.

Thanks, Bruce
