WOW!!!!Found something very interesting....http://motorcycleinfo.calsci.com/Filters.html
WalMart SuperTech ST7317Same exact filter as the Mobil 1( made in the same factory by the same machines)---Walmart $2
I noticed in that article (a reference to which was posted many moons ago) that Wix was one of the recommended filters. I tried one and it leaked like a bad diaper. Put the OEM filter on and all was fine. Yeah, I could have got a bad one and the rest of them may be just fine, but, I'm not taking any more chances. I will, however, try one of the afore mentioned filters that everyone seems to like.
