Hello Rollerfriends, Our Yamaha Aerox 50 from 2006 with almost 9000 km on the clock no longer pulls! Prehistory: The scooter was throttled by the previous owner at 25 km/h, especially by a distance ring in the Variomatik and one with the designation CDI FS Neos/25. We throttled the buck, so ring out and CDI replaced by an open CDI. Before good suit up to 27 km/h, then close. After our operation from 0 to 20 km/h in felt 2 minutes, as well top 20 km/h????. So, sch once Schei..e, mountain with slight climb not 10 km/h, waaaaruuum. Motor or wat, I have no idea. Recently made: head seal as well as piston rings, new spark plug, nothing else.
