2010 Kawasaki Z1000 Motorcycle Valve or Timing Chain Noise? (Fixed! See Video In Description!)

Описание: [Problem Fixed!] The clicking noise was caused by lose exhaust pipe manifold bolt. See this updated video for explanation:    • Motorcycle Engine Clicking/Ticking Sound? ...  

I hear this clicking noise during ridding and engine idle, not sure if this is the normal engine noise or the valve/timing chain tensioner needs service?
