Nope, it's the chain slapping the chain guide against the top of the swingarm (right behind the countershaft sprocket).

On the earlier WR's, we loosened the top half of the chain slider and inserted a piece of rubber under it (padding) then tightened it back down. This took care of the noise, and prevented the chain slider from wearing into the swingarm.
