Yes, I have never seen any probs with these either
There will be a reason Joseph Lucas was always referred to as the "Prince of Darkness" . . . . back when I had an old K-series Bedford and my friends had old Bonnevilles and Saints and Nortons and Matchlesses etc (we're talking circa 1975) one of the commonest requests I used to get was "Mike, can I borrow the K to go collect the (enter Norton, Triumph, BSA to suit)?" and the Prince of Darkness was usually referenced as the cause of the problem . . .
FWIW my experience with the automotive inline small, sealed filters is that some are for various forms of common-rail engine and their one-micron (or sub) filters don't serve older, gravity-feed systems well. I don't know how you'd tell which one was five microns and which was one? Either way - I'd guess they are more filtration than you need?
