KTM 640 LC4 - Loud clicking noise when idle

Hi guys,

Can you help me to identify source of loud clicking noise I can hear when idle?
It goes away if I rev a bit and comes back when engine is back to idle.
It comes from exhaust valves area. Can it be automatic decompression ?

Any idea? Is this something to worry about?

This is story has a happy ending.
Jump straight to the final chapter if you are in hurry.
