Engine rattle!!!

Not long got the bike out this year ( a little later than usual!!) had the valve clearances done last year and she was running sweet, i have noticed that when i start the bike up there is a rattle from around the front of the engine, put a slight rev on and it dissapears, it sometimes lasts for a little longer than i would want but does always stop, now i assume its the cam chain tensioner, any ideas if thats the culprit or not and just how major a job it is to replace? The bike is a 2011 model with around 12,500 miles, maybe time for an upgrade to the 1100 :D:D:D
 
Yeah, sounds like the cam chain tensioner not working correctly, unsure as to just how major a job it is to fit??!!
 
Could be just a lack of oil on start up. My R1 had the same rattle on starting, Yamaha changed the tensioner design so that it holds oil when not running.
