Affected models are 6004, 6005, and 6017. The 6004 and 6005 are cartridge (internal type) and the 6017 is a spin-on. The 6017 has a faulty crimp attaching the filter can to the base. The 6017 is what FRAM suggests for the Honda VFR750 (among many other bikes).
Here is the text of a posting to the racing mailing list with further details. (I did not write this.)
