I just bought a used 04 Z 250f it started feeling like my clutch was slipping so I drained the oil I realized it had a metallic look to and sure enough their is very small metal shaving in it every where. I looked at my clutch system and the friction plates are about half way shot, they measure .115 . I need to Know where the metal shaving most likely are coming from and i dont think it is from the Friction plates. help!!
