Hello friends,
        
 Yesterday I did a valve adjustment (again), after the first time failed.
         
        
 When I turned the engine (counterclockwise) I noticed a certain free play, a clicking noise.
        
 This is my first bike, and I do not know whether this is normal or not, would love to hear what you think.
        
 What is the reason for that noise? Is this normal?
         
         
        
         
         thank you.
