I bought a Speedfight 2 yesterday. The seller told me some flaws that were easy to solve. After a small test drive the scooter went out. The reason for this was that the cold was called. The scooter got new pistons and cylinders and many other things. These were already driven up to 200km. I meant not to pull the speed so high but to drive 100km slowly. I also kept the return drive home but after just under 5 minutes The scooter went out. Went back on but completely overheated. I found that it didn’t cool properly. I had the same day drive back directly with a trailer and brought it to the workshop and thought that it could be repaired because only the cooling system didn’t work. The mechanic has now told me that the gearbox, gearbox output shaft is crooked and grinds at the rim. Water pump is also broken by the overheated The water tank has holes so that water splashes out. I noticed also in the village after less than 5 minutes driving with the water tank. The scooter did run and also came around the 70 km/h. I wonder now if the cooling system can be repaired and everything can be rebuilt so that everything fits well or it was recommended to me that the seller should take the scooter back. buyer no longer answers and I am afraid that I have now made a bad loss. There was a purchase contract with everything said that there is no guarantee but in case of hidden defects this falls away. What should I do now ?? Please help me.
