I decided to take the plunge and service my Exup and what a nightmare it's turned into
i think the previous owner had decided to service it himself and possibly may have lost some of the components upon dis assembly and the decided to just bodge it back together, the only plus side to this saga is all the bolts came out easily. Firstly the pulley centre bolt had been replace with an Allen bolt which rubbed on the inside of the cover, then there was no washer but there was a spring which was half worn away, then there was no spacer at the rear instead just the worn remnants of a stepped washer and the bushes and valve worn very badly.
I managed to get a good used valve and front plate off the flea bay but the front plate has snapped cover bolts so I think my best bet is fit new bushes to my plate and downpipes but they look well tight in there. Is there any easy way to remove/replace the bushes or would it be easier to drill out the snapped cover bolts on the replacement which is a good fit with the exup valve then all I've got to do is replace the rear bush on the downpipes
I've attached a few pics to show what I found, the 1st one is what replaced the rear 3mm spacer
