Just wondering where past posts can be found or how to find info on opening up our air filter box?on '06 CRF250X.
Thanks for any and all help !

The procedure is the same as the 450X , some people just remove the snorkel some cut the whole top , some cut the top and sides , its all a matter of preference , but it needs to be done in conjunction with jetting
