BillWilson. Make sure you consider doing UOA's when changing oil. I think you'll find that an OCI based upon 2k miles is excessive changing. Changing oil too often could be detrimental, just as not changing oil soon enough.
Google the SAE website. There are many technical papers there. You have to pay to view them. They are copyright protected, and I tried to get permission to use one once and they denied me initially, and then would only allow me to quote large portions of the paper if I fulfilled a large punch list of legal criteria. It wasn't worth the grief.
Bottom line is this: you can acutally change oil too often. The wear patterns are higher right after an oil/filter change, then drop over time, before growning again. There is also an unofficial oil study done by some guys to see how Mobil 1 and Amsoil stacked up in extended drain intervals. Check out this site and read all the related sub-pages. In there, you'll see they documented engine wear would go up after OCI, only to drop off there after. They also referenced the SAE/Ford-Connoco article. Here's the links:

They aren't SAE engineers, sure, but their reading is not objectionable, and they didn't do a 1/2 bad job from an analytical point. They made statistical errors, but overall, it's a good read. Here's a quote from that study: "Engine wear actually decreases as oil ages. This has also been substantiated in testing conducted by Ford Motor Co. and ConocoPhillips, and reported in SAE Technical Paper 2003-01-3119. What this means is that compulsive oil changers are actually causing more engine wear than the people who let their engine's oil get some age on it."
Bottom line is this: you're definitely wasting money with a 2k O/FCI, and while not likely, are you are possibly doing harm.
Stick with your OEM OCI, and use a quality brand name application specific filter, and you won't have to worry about the bike. Wix specifically recommends a filter for your mount. If the motor/trans fails due to the filter, they'll cover you.
I don't care if you use Wix, my point is to your initial post. I don't believe for a moment that the Suzuki filter is, by design, proprietary. And Wix is one of many brands that actually recommend a particular filter. Use them with confidence.
