Its possible , that is the Judder Spring , my opinion is the first chance you get , go to the dealer , get a extra fiber plate , remove all the Judder Spring crap , and replace it with a regular plate , your clutch will last longer ..... That is the first thing I am doing when I get my new 450R , is request a extra clutch disk , and put that in before I even ride it ..... for the life of me I don't get why Honda won't go back to the 08 clutch , everything since has been iffy at best .... especially since the introduction of the Judder Spring ..... and the 4 spring clutch .... that was sad .........
Anyway , How is your clutch lever free play ?? , I see no reason for a rattle , and if everything checked out , it might be a adjustment issue , if it is over adjusted it might cause the clutch to override and that might be the noise .......
Also , not sure if you still have the cover off , but try pulling the lever with the cover off and see if you notice anything (with the bike still laying on its side) when the lever is engaged/disengaged
