Stainless reusable oil filters
A riding buddy makes those filters. Not exactly his words, but here's my take on the subject. The medical grade stainless filter mesh traps particles down to 35 microns. A paper filter is both better and worse. Inconsistency is the key. It may trap smaller particles in one area, allow larger particles to pass elsewhere. There's no disputing the stainless mesh flows more oil. Where this matters, is on a plugged paper filter, the bypass opens, allowing UNFILTERED oi to circulate. The idea mentioned by one rider, is to use BOTH filter types at the same time. One stainless, one paper. On each subsequent oil change, you swap locations. You use half as many paper filters. Still have to own both stainless filters. But get the best of both worlds in oil filtration.
Meanwhile...on the paper front, K&N is making the filters now. Less expensive than stock by quite a bit, but also more pleating, thus more surface area for filtering. Looks like a very high quality product.
