Moin Aprilia SR50R Bj 2011 Carburettor model with approx. 10,000km down and in original condition As soon as you give full throttle the scooter sucks off, i.e. there is no gas. But if you give only a little bit of gas it drives. However, it does not go out and runs through also in the stand. When I bought it (used) it was throttled, i.e. no gas train/gas tap throttle and no distance ring but otherwise everything original according to previous owner (!) and you could give it full throttle even without problems. Then I put it on 25s throttled a gas pull-off throttle and a distance ring in it. A few days later the distance ring out again and the gas pull-off throttle still left in it, it ran normal. Then also the gas pull-off throttle out and since then I have as I said the problem that you can not give a full throttle. It squirts quite neatly, the exhaust end is somehow damp or hangs there an oily liquid or something and it smells a little. (But that also at or shortly after the purchase) My Presumably: He runs too fat (too much gasoline) and the previous owner has changed something at the carburetor, because he swallows in my opinion also relatively much gasoline. It’s just my guess, don’t know me well with scooters because I’m a beginner therefore I absolutely need the help of people who know each other! I ask for help it is really very urgent so guys are dependent on you!
