Clicking Sound When Bike is Turned off??

[yammieman]

hi there. im just wondering what the clicking sound from the video link at the very end, coming from the bike is when it's turned off?
mine does it too when turning the bike off but really noticed it was abit louder when i was trying to get bike into neutral and it was still in gear and stalled as i let clutch out as it was obviously still in gear(hard to get into neutral when bike is running). so just wondering what the sound is/what it's coming from and if it's ok and won't do any damage to anything?

Metal expands as it is heated and contracts as it cools. All you are hearing is the normal physics of metal as it releases tiny built up stress points caused by the metal expansion.
