I have a spin-on filter on my 1977 350. Mounted with some clear hosing connecting from and to the rocker feed.
Flow of oil, both in and out of filter, as seen while bike is running in neutral is not constant...sometimes dribs and drabs, sometimes nothing, sometimes a series of separate blobs, sometimes a constant stream of fluid. RPMs help; the fluid moves faster, but it never settles to a constant. Can't tell very well while riding, but seems generally reassuringly brown in the lines when I glance down. No problems with the engine so far in 160 initial miles.
One factor may be the wider inner diameter of the vinyl tubing compared to the feed lines. I thought it'd be self-regulating once oil had fully circulated through the system and primed (both) filter cavities. Am I wrong?
Am I killing my engine, starving it for oil? Do I need a high-output pump if I'm going to run this thing? I'm getting a bit nervous and thinking about ditching the filter and slapping on a standard rocker feed line.
Thanks-
