my son was driving it down the back road at 20kms. it just made a bang and locked up. he tried to start it but it would only click not turn over. he had it towed home about a 1km. he left it sit till i got home from work , i tried to start it it cranked over and started, ran for a min then stalled. it restarted but runs but is making a noise. dealer said its probability the wet clutch. i just took it apart and the wet clutch looks ok. there is a lot of metal on the oil plug magnet. so i think its more then a wet clutch. so do i ripe it all apart.
