I Have been following the "Raptor Forum" for months. Thanks for the tips and ideas. My first post. Got my Raptor October. Now, after every ride, the air filter is coming off. I remember a while back someone said the same thing. After close inspection I have found wear marks on the top of the air box lid from the 3 cross supports under the seat. And NO, its not my fat a$$. [ 200 lbs.] Might be able to shave them down a little, but still.... back to Yamaha I go tomorrow. Other than that.....
