Servus, my Aprilia SR-50 AC WWW Bj. 99 loses almost the complete tank content via the overflow valve. I bought the scooter on Tuesday used by Private for 400€. It ran 7,000km and is technically in good condition. I filled the scooter the day before yesterday and drove since the 15km and the tank is completely empty. In addition, a large petrol-larch has formed under the scooter. The scooter actually loses permanently gasoline, no matter if in the stand at running I have already been able to collect a lot of information on this topic in the countless existing forums and have come to the conclusion that either only the petrol screw has to be tightened, the float needle no longer works or the petrol tap is defective. Unfortunately, I have no experience with the disassembly or reperation of rollers. I then tried to remove the clothing in order to improve on the engine. the swimmer to be able to tighten the petrol screw, but it seems to me that I have to disassemble the bench. Now to my actual question: 1. Could you tell me with what I should start over and best still what I have to disassemble to get to the spot 2. What else could it be that the scooter loses so much gasoline? Unfortunately, I can’t afford a workshop at the moment.
