Cause for uneven front sprocket wear?

[TransNone13]

I noticed uneven wear on my front sprocket today (rear is normal and I checked rear alignment). There doesn't appear to be any leaks (no bent shaft), and well other than that I'm not sure what's going on. Bike has 700 miles on it. I think I may have bent the sprocket, thoughts?

I don't know what would cause that but if it's only got 700 miles it could be covered under warranty?

Have you checked to see that the rear wheel is aligned properly? (You might have said this in your video, but I don't have sound)

I did, I loosened and and reset it. The wear isn't off on the rear and you can barely make out the front rotating untrue (at least I think so).

It is under warranty still, I didn't want to, but I suppose I should bring it in.

There is a countershaft issue with the drzs. Check this link: http://www.supermotojunkie.com/showthread.php?117398-Pics-and-Video-of-a-Countershaft-sprocket-seal-failure-while-ririding heck to see if there is any free play with the countershaft bolt.

First thing I did, tracking the issue. I leave my sprocket cover off for easy inspection/cleaning.
