Hello dear user Unfortunately I have a problem with my scooter and just can’t get any further… First time to the scooter it’s an Aprilia SR 50 R carburetor model with just 1400KM mileage. I bought it recently it stood quite a long time before it. I threw on the scooter and wanted to drive off. I immediately noticed that it was running crappy. Could only drive partial load and there it stuttered already from time to time and at full load it drained off. He had a 25kmH throttle. I had a 25kmH throttle. ch removed the Variomatik ring and the gas slide throttle, whether it ran well before I can’t say because I already throttled it before first operation. Since it was standing for a long time I thought to clean everything. Carburettor taken out all the nozzles with brake cleaner flushed through everything meticulously cleaned and also installed a new candle. Membrane also controls everything in order. Everything built on it still the same problem. I took off the vacuum hose and the petrol achlauch and ran at the vacuum hose sucked fuel. Then I put the vacuum hose on the carburetor and left the petrol hose outside to check if it shoots sprite then. I turned on the scooter and yes it works too. The scooter is unbasted all original except the thrushes I have removed however. I can’t imagine that it runs too greasy as I said unbasked HD is 53 or 52 doesn’t know exactly what the original nozzle is. Why doesn’t it run clean? Why does it drain at full load? My knowledge just stops there unfortunately. I need your help
