I could do a search, but I am simply trying to stir the pot. I have an 04 wr450 and love it. Just installed the yz exhaust cam, feels like a new bike. Anyway, he has the 07 and we rode in southern TN two weeks ago. It was like a dust bowl. It was the most dusty riding i have ever done. We rode three days and on the third day he was cleaning his filter for like the sixth time and said "hey, there is a hole in the center of the basket. I guess the yz has a bolt that goes through there, but the wr uses a spring type bar. His bike sucked dust for three day cause he was never up front and his titanium valves are probably roughed up. My question is, are all you 07 owners finding this error and what are you doing about it? Are the dealers taking care of you? Have you had any serious failures.
