Here is the low down, when I pull the clutch in the chatter goes away when I let out while roll the chatter comes back. Any clue?

 

I have a new kfx450 and I noticed the difference in the noise when I pull the clutch in while not in gear a few weeks ago. In the past week it seems to be noticeably worse which is making me paranoid, LOL

Wondering if you found anything out about your clutch chatter on your 400.

Thanx
