[QUOTE="davidd, post: 129442, member: 1177"] John, I would guess that there was a restriction in the steel pipe that runs from the return up to the filler neck. I had the pulsating when a nylon ATD tooth came off and worked its way to the return. It was too large to go inside the pipe, but a bit of debris or gasket goo could have done so. It sounds like it has been cleared, which is good. It is a shame that Vincent did not filter the oil return as it pumps a lot of debris back into the oil tank. [ATTACH type="full"]38099[/ATTACH] I did this on the racer, but I had the room under the tank. The return line ran up to the filter and then the filtered oil came down to the return on the UFM. This has been done on some street bikes by mounting the filter on the RFM pivot (bottom side). It was done on a few Series A bikes for cooling, not filtering, but the filtering cannot hurt.
