- Quite often, owners have to clean the throttle and idle valve;
- Also, the filter mesh in the tank is regularly clogged and the fuel pump fails;
- Sometimes the timing belt and its bypass roller do not live up to the scheduled 120,000 km;
- Due to the lack of hydraulic lifters, it is necessary to adjust the valves every 100,000 km.
