Hello, I bought an Aprilia SR50 Alex of the Angelis Edition 2 weeks ago. BJ. 2007 mileage almost 9tsd Km. The scooter stood with the previous owner long and was driven only little. The front tire was huge and I decided to give the scooter to the Aprilia dealer to have a new tire pulled up and to have everything checked through. It was also diagnosed a cracked carburetor flange and a cracked suction socket and was exchanged a ne The workshop was able to check the rollers and diagnose them for good, put them together again in proper clean sequence and probably greased the rollers??? Before I put the scooter there he pulled very well from the start to 50kmh like a small rocket then there was a short break and he moved on to 80kmh. Now after everything was exchanged he pulls much worse from the start but then from approx. 35-40 kmh constantly powerful up to 80 kmh. At a certain speed it will go just before it starts (probably the belt slips through) and then starts with moderate speed and tolls a lot badly as if you start with the car in 2 gears….. afterwards it hangs well on the gas? After I picked up the scooter and drove the first 5 km I turned around and wanted to complain. The workshop master told me the scooter is driving well and he would not notice anything. He means the scooter pulls but I am meanwhile 80 km and it hasn’t really improved. Do you need to get in or ahead of it? Should I go back to the workshop and ask for a repair?
