I have four shock absorbers of varying provenance. The original Vincent one is totally shot and needs a full rebuild or throwing in the bin. I then have a couple of KONI and IKON units. My problem is that NONE seem to have have parallel eyes. If I fit the relevant studs into one of them the other will not line on. All mix sort of but NONE fit. I think all the eyes on these dampers are not true and so I am having a real problem with my rear end (SHUT UP!) .. The IKON has a bushed rear mount BUT the front mount is then the issue. The Koni units are not bushed at all. There is nearly 1/32-1/16 interference with fitting a stud between two of these, let alone trying to fit on an RFM!!! Has anyone else had issues with fitting? I have checked the alignment of the RFM with the UFM with a 3m straight edge and it is "very bloody close"! Any input welcome.
