After some advice/guidance....I've just changed the drive belt on my 2006 Scrambler 500 4x4, and when doing it I noticed something seemingly rattling around inside the driven clutch. I've taken the clutch off and given it a little shake, and it does sounds like something is loose inside, I'm assuming there's not a lot of "free space" inside the clutch as it doesn't rattle loads...but I cannot for the life of me get the thing apart. There's a circlip/retaining ring on the backside holding it all together (see image)...does anyone know if a) its worth the hassle to getting the clutch apart to find the rattle (assuming it shouldn't rattle), or b) how you're supposed to remove the circlip/retaining ring.

Bike has been running fine, no issues, just doing some routine maintenance.


Appreciate any help/advice anyone can give me!
Thanks
