Hello people have been having a scooter for a few days now. so far everything is okay, but I have a big problem with the gas grip, if I give gas and then let go of my hand he doesn’t turn back. grip stays in the position where I let go of my hand. so on full gas e.g. he has to turn back again manually so that he is up again. Did any of you ever have such a problem? how can I fix this.? Can’t really sleep at night because of this sch**** Vi thanks in advance
