You can confirm by pulling the cam over and see if the chain has been slapping it and leaving marks.

Two parts oil, one part Oat Meal, should do the trick.

At an event, I started listening to all WR's and noticed that 9 of 10 rattled to varying degrees, most not a severe as mine, some worse. From that info, I mistook the rallte as normal.
Finally toward the end of this summer, about 1000 miles later, an intake valve broke. Damage incurred: about $1400.00 in parts.
If you don't find the problem elsewhere, I suggest you remove the head and have an expert give it a once over. Or wait like I did and pay the ultimate price. Although you don't hear much of broken WR/YZF valves here on TT, it appears to be not too uncommom after talking to mechanics and specialty shops.
