I've got a 1992 FZR250r 3ln, and am looking for a OEM air filter. I can't seem to find OEM OR aftermarket. Is my only option to get some pod filters and fabricate a new air box? Do you know where I could find either a new or very good condition OEM filter so I don't have to change setup and likely re-tune? Thanks and please let me know if it is inappropriate to write this here, I'm new to the forum.
