Thanks for the help so far guys. I did remove both draining bolts. So I get home today and start the bike up (after checking oil level and any leaks) and the noise has disappeared completely.... 
        
 
         
         
         On another note, I decided to fiddle with her and installed the centre stand, optimate charge cable, h&b bash plate and a denali powerhub 2, 
         
         
        
 
         
         and just as I was finishing the jobs, guess what I see: dents on the frame! On a brand new bike as well. So disheartening.
         
         
        
 
         
         Any suggestions as to how I can sorry this out? I've taken pics and sent an email to the dealer. Will probably call him as well first thing tomorrow.
