Am just starting to reassemble the steering stem on my 1984 VF1000R. Along with the lock nuts there is a seal that is similar in looks to the top seal but smaller. See the photos - the seal appears to be worn down on the lip and missing rubber. This seal will fit over the threaded parts of the stem but no further. It does not appear on the parts fische either. I have the top and bottom seal but can anyone identify this seal and where it might belong? I do not have a grease holder ring either - is this important?
