Just got round to looking at the sprocket cover to investigate the clicking clutch.
After taking out the rubber bung from the cover it was noted that there was particles of rust sitting under the nut, which wasn't what i wanted to see.
So, i then followed 'unfazed' instructions and undid the nut then took off the sprocket cover, unbent the tab and released the cable and took the spring off.
If you look where the nut was and at the same time work the mechanism behind by hand you can actually see the bearings as it moves up and down.
I used brake cleaner spray at first to give it a good clean out whilst still working the mechanism up and down and the rust started pouring out, so just kept doing it until the liquid became clearer.
Then, using the same technique, i sprayed white grease into where the bearings are, still working the mechanism up and down until it appeared full, which was actually quite a lot of grease.
Whilst the cable was off i removed it from the top end and used some 3 in 1 oil to give it a good lubing until the cable movement inside felt very smooth.
After putting the cable back on the top end i screwed the cable housing in to leave a few millimeters gap so i could adjust it from the bottom end instead.
So after putting the cable, spring and sprocket cover back on you can then adjust the cable.
You need quite a deep angled 12mm ring spanner to do this.
The manual shows you what to do with a picture, but for the record, put the nut back on without tightening it up, then with a cross head screwdriver turn the centre screw all the way in until it stops then take it back out by a quarter of a turn then tighten the nut up with the ring spanner whilst holding the screw in position.
If it's still not quite right then you can adjust any slack at the lever end.
And then...........
NO CLICKING and a very smooth clutch movement
. I think it's another one of those things that creeps up on you so you don't really notice it, but if you've not ever checked it before, which is unlikely, then i would say it's definitely a job worth doing just for the sake of it.
Thanks to 'unfazed' again, as his instructions were very helpful
