Hi, I did a search but I couldn't find an answer to this. Background: just got an XR650L. It has a K&N filter in it. I want to get rid of this. It is of the paper/accordion type. I also own an XR250R, and I like the foam filter + metal support/ backfire screen system. I emailed a Uni filter vendor and they said that the foam filter does not come with the metal support, and that they did not sell it. Any idea if a metal backfire screen is available for the XR650L for use with a Uni filter? Thanks and sorry if this is a repeat. d.
