2007 FZ6 25,000 miles

So I noticed tonight coming home from work that everytime I take off from a light I get a nasty grinding clunking noise, none of this has to do with the normal chain noises and its not shifting noise. It is real bad in 1st and only in low RPM in 2nd as far as I can tell. To me it sounds like gears grinding or something. I am going to take the cover off the front sprocket in the morning and see if anything looks nasty. But what do yall think?

Pulled the cover off the front sprocket and the teeth are curved, but the sprocket isnt loose. I am betting my chain is worn too. I am new to motorcycles so I don't know. I adjusted the chain to factory specs a few weeks ago and cleaned and lubed it.

This noise just started today out of the blue. its more of a feel the grinding through the frame rather than hearing it.

hey man you ever figure this out? Having the same problem replaced the chain now again the noise is back.
