Hello together, I am at a point where I don’t know what to do. I don’t want to throw away the scooter either. I have a Piaggio Sfera 50 NSL. Some time ago there were problems with the electrics whereupon I changed the alternator. After about 50 km driving with new alternator (and without any problems) he started to stutter etc. Having arrived at home I noticed that fan wheel (which sits on the alternator) has fallen off. I didn’t really like this. This is how I don’t get the car running anymore. Mega starts off badly and when it goes out quickly again. I asked at different places and everyone gives you a different tip, so I tried and renewed the following things. Air filter cleaned and new left battery new spark plugs new carburetor new shaft sealer on alternator side new with and without exhaust started cylinder, piston new suction nozzles new bis z My hope was that with my new cylinders (compression with the old 5,0 ) something was going on. But here the compression is minimally better. Should I change the alternator again? (With light etc. I have no problems anymore) So slowly the money runs out.
