* UPDATE 10/10/2017*Brad's FilterFix
I checked in with Brad about the availability of his FilterFix, here's what he had to say, "I just sold the last one I had about two weeks ago, [Sept. 2017] and it looks like that will be it for now. "
Brad followed up with a post to the forum thanking everyone who purchased the now limited edition FilterFix: http://www.xs500forum.com/index.php?topic=2042.msg10913#msg10913
It appears that the Tru-Vantage is no longer available. From CrouchyUK, the forum admin, "...was marketing the Tur-Vantage adapter for someone else- I am sure I read somewhere he can no longer get them." I looked around and it appears to be no longer available.
I just have to say that this is a hobby not a business and many thank yous to Brad and Uncle Fuzz for going way out of your way to have these parts manufactured and all the logistics it takes getting them sold and delivered.
It appears that the torch is available.
In the mean time, keep an eye out on ebay for NOS adapters. (part number are below) and/or change your oil frequently to get the most out of your old-OS filters.
