When moving the bike either back or forward, I have recently notice a low (as in a low/deep sound) clicking noise coming from the rear. I am certain that i can feel it though the rear seat when I am pushing the bike.
I havent had a proper look yet, or had the bike up on the stand, just thought I would ask you guys first.. Any ideas?
2) A knackered circlip groove in your sprocket retaining flange.
Antonye has posted about this several times, so do a search on 'rear hub' or 'sproket flange' and all will be revealed!
I did the cush drives a month ago, and have just fitted the later type spocket flange as the clicking had continued - now all is quiet and as it should be in rear hub land!!!
