Hello dear forum, I have a problem with my Aprilia SR 50 LC Bj. 2006 with Piaggio engine. 1800km down, all original except ZK and battery, according to previous owner all throttle inside. Now to my problem: I bought the scooter about a month ago. The scooter actually ran quite well, but had sometimes (irregularly) a bad suit and he also did not take a full full throttle. So if I gave 100% gas, it felt as if it was drinking off. because of this thing I wanted to clean the carburettor, because I thought it was because it was something clogged in the carburettor. Carburettor removed, everything was cleaned with carburettor cleaner and again reasonably assembled. But so far the carburettor looked quite good, nothing clogged. When I was working on it, of course, I looked at everything on cracks etc., ASS had a small crack but you couldn’t see through it. n (no light), membrane ok, hoses ok, air filter matte cleaned. I then brought the carburettor in basic setting, and wanted to start the scooter. The ging then kick after about 10 times, but then I went out immediately. Air screw further in turned, again 5 times kicking, scooter went on, turned extremely high and then went out again after 1 minute. I thought that first the gasoline had to refuel, so again hard to kick (over 30 times) and the scooter did not come at all?! n a short break made a smoked (5min) and then tried it again. 2 times kicking, scooter came straight but turned up again extremely high, so air screw out a little bit. The scooter then ran a little quieter and went out directly. I then tried to adjust the carburetor but without success. Had the assumption that it is wrong air (ASS crack) that it does not run. So new originals ASS ordered, yesterday he came out then. Yesterday so again complete carburetor out, NOCHMAL all Saub All assembled, same problem. Roller goes on, then turns extremely high, then runs only 1 min and dies. I controlled the vacuum pressure, so if you suck on the vacuum hose you get gasoline. I can only keep the scooter alive very hard, so I have to play carefully on the gas that it stays on. With more gas it also goes out directly. Unfortunately I don’t know what this can be about and hope you have some suggestions about what this might be about. I am grateful for every piece of advice!
