Anyone used the PC Racing FLO PCS1 spin-on oil filter? Specifically, I'm wondering if that's the correct one for a 640 Adventure. There is some confusing information about what exactly it fits, as in, fits a Duke 640 and a 990 Super Duke - huh?. My 950 is the same basic engine layout as the 990, and there is no spin-on oil filter of any kind. I actually have been using a scotts stainless spin-on for many years, and it works great, but is very difficult to get off (no nut), and more difficult than it needs to be to take apart. The PCS1 looks easier on both counts, if it's the right one.
