Hi there.
        
 Has anybody got a clue about how to eliminate those irritating exhaust blasts/knocks (hope I 've used the right word). 
        
 Here's a audio track to show you what I am talking about

 Is this happening due to poor combustion, and can it affect the engine's reliability in the long term?
        
 My ten has done 3000km already.
