Hello people My son man drives a Generic G50 throttled. On the way home he suddenly had performance loss. After that he did not jump on. After that he tried here and there and then he jumped on. In the empty run no problem. Bergrunter everything still ok but then again uphill performance loss and went out. I noticed that the kick starter somehow crunches and is very difficult and no longer comes back by itself. Has anyone ever had this before? LG Claude
