Hey, my first question here. Let’s start the story from the beginning, a couple of months ago I had changed my belt and thus weight the Vario and have so far driven without any problems. Today at a junction at a stop sign I stopped, and when I started driving (full throttle) I managed to speed up over 2 meters but then the engine is off and did not accelerate any more. Unfortunately, I didn’t notice any noises. There is mpression, from the exhaust comes bursts. Ignition does nothing, petrol is there and rear wheel can be turned. Roller is now standing in the city. I have no explanation what it could be because something like that is driving me again for the first time, and could not help me AI also To the scooter: 4 clock Alpha Motors 50cc What could it be? How do I recognize a crack of the belt?
