Sir there is no cable in city's clutch.its hydrolic clutch operated by oil. if the sound isn't coming from pedal, its coming from the point where the oil actually operates the clutch.its there in my car too, n its there for long time.i ve got 100s of washes but it didnt go away.talked to honda 3s guys n they said they can lubricate it but the oil will reach the clutch plate n will cause clutch slipping.i dont know if thats true or not cuz i dont believe those 3s honda guys at all but this may make some sense... so, just live with it i wud say.
