I bought my first Suzuki in 1979. I learned about their stupid proprietary oil filter about a week later, at my first oil change. I've been deeply annoyed at this ever since.
For the record, I'll be talking about a product in this post. I designed the product, however it won't be me making or selling the product, nor will I make any money when they are sold. My reward for my design efforts is that I got several prototype parts for free; that's the beginning and end of my involvement with this product. After all, it's apparently illegal at this site to publicize one's own product.
I now have an adapter on my VStrom that lets me use industry standard Honda type filters, like the Pure One PL14610 or the Supertech ST7317 (shown). These filters, as noted in my filter xref page, have synthetic media and are about 8 times more efficient at cleaning your oil than normal filters, like the Suzuki OEM. They also happen to cost less, but my purpose here is cleaner oil, not saving $8 per oil change. It also means I now only stock one oil filter for all my bikes - VStrom, ST1300, Superhawk, Ninja650. This adapter will fit any Suzuki 4-stroke engine, including motorcycles, marine outboards and quads.
I expect this product to be available to the public by Nov.1, 2010, for under $20. The guy making them is still working on his web site, he's not quite ready to take orders. But they're on his VStrom and mine.
Sorry about the dirty bike. My VStrom is now ridden by my 20 y/o son and has 74,000 miles on it. Like most teenagers, cleanliness is not among his outstanding qualities.
