I just bought an 07 crf150r and i drained the oil and it has small little metal flakes in it. they have a gold color, but i cant think of anything that is made of brass or copper that would be this color and is in the transmission. The bike runs and shifts perfect. the only thing i can think of would possibly be the clutches. The guy had just installed new ones before i got it from him.
Ill be flushing the system and pulling cover off to inspect it all, but if this is a common problem i cant find anything about it.
Does anyone know what would cause this? Thanks in advance
