!loud cluncking sound if i am not smooth with my throttle coming from the rear end..
 

I am hearing a loud metalic/clunck whenever i open,close the throttle ,especially at low speeds, coming from the rear end.
yesterday i noticed that i hear the same noise/clunck if i brake hard and lock the rear wheel alone (while applying the clutch)

i tried searching on this forum and found some members who had the same issue, but since i am a novice , i need some help as i am not very familiar with the bike yet :icon_shrug:
any ideas?
