Hi All
I seem to be getting a loud clicking sound from behind the front sprocket cover when I pull my clutch in. Cable and adjuster both set as standard and the mountain of gunk behind sprocket cover has been removed. Push-rod moves freely. It still happens.
I seem to recall that some on here are not fans of non-original clutch cables. I am - the originals are 30 quid now according to fella in local dealers! However, could that be the cause? I must admit to being stumped by this one......... It seems to run OK but I don't want any long term damage.
Any suggestions gratefully received.
Stay safe out there.

Does the clutch operate normally? Is the noise definitely coming from the sprocket cover? Did it start making the noise all of a sudden or has it gradually got worse? Any damage to the cover itself? When you pull the lever in does it return normally when you let it go?
-
Thanks for your reply. Answers in order of your questions:
It seems to..........
Yes
All of a sudden
No
Yes, the noise happens when you pull the lever; it returns normally.
Imagine tapping the edge of a coin on your table - that is what it sounds like.
-
Is it a single tap or a continual tap tap tap? Does it happen when stationary or moving? Does it only happen when when you put it in gear or all the time when the lever is pulled?
-
Single click/tap noise. Didn't notice it while riding (too noisy), but in the garage while parked up. I pulled the clutch when routinely checking free play and heard it then. Repeated 10 times and it always happened. A loud single click/tap as soon as I pulled lever. Definitely coming from behind sprocket cover.
Assume it happens every time I pull the clutch in/change gear while riding but I can't hear it over engine running.
Bizzare :eek
I could replace the cable (again for the 4th or 5th time) but am loath to - how many times can you change a cable before the locking tab behind the sprocket cover (that keeps the nipple in place) breaks through being opened/bent back too many times? Knowing my luck........... :'(
-
How clean is the back of the sprocket cover? mine would click/pop when I pulled the clutch lever, since I cleaned greased the actuator its a lot quieter and smoother.
-
Cleaned it but makes no difference unfortunately :\
-
There's not much to the clutch in that area, just the cable and the mechanism that pushes against the push rod. Maybe try taking the cover off and hold it so there's tension on the cable then pull the lever a few times and see if there's anything out of the ordinary.
-
Check the nipple on the lower end of the cable is located properly in the actuator mechanism.
Theres a tab on the actuator where the cable goes that makes the nipple a little awkward to slot in properly , clutch will still work but the cable moves about a little causing the click
-
Yep what gassitt said
Here is what I have found as last week i gave it a clean of its life
The tab "C" has to be bent down to enable enough slack to push the cable down enough to slide it out of the slot. The area between "A" and "B" will not pass through the slot as the slot is only wide enough to let the bare cable pass.
If your tab has not been bent back up after removing the cable or if it has snapped off. then your cable nipple part "A" will fall below the hole at the end of the cable slot, when you then pull the leaver point "A" catches on the slot/ hole and then slips off and catches onto point "B" with a "click" where it should of been all along and helped to stay there by the tab.Or it is even doing the same but catching on what remains of a broken off tab.
Also the photo looks like it go's in from the front but it dosent - it slides in from the left like the diagram
Hows That !!

I think you missed something out... :rollin

I've got this bloody clicking now, i actually thought it was the lever end with the crash helmet on, but obviously not!
Just had the sprocket cover off (nut's still there, werhooo) and cleaned it all up, bent the tab up a bit more so it was touching the nipple then put it all back and it still clicks, quite loud actually as well.
Started rapidly running out of daylight so i'll have to have another look at the weekend now.
-

Well that chucks my theory out the window then. Take the cover off - let it dangle and pull the leaver whilst having a close look, you wont be pushing the rod but can see if its anything at the nipple end
-
Your theory did sound promising, and is still feasible, but it still clicked?
Need to examine in in good daylight.

Out of curosity what mileage is on it and do you use it in a lot of start stop traffic?
-
Mine's 42k and always in bloody traffic, what's your theory unfazed?
It's an OEM cable too, and not that old.
-
Mine had a similar problem a few years ago, the action felt rough through the lever too.
I found about half the ball bearings in the actuator were knackered. (It's easy to mash the heads of those two screws, heating the alloy casing up a bit first helps.) Luckily I had some bearings of the right size and the helical grooves in the mechanism weren't too badly affected… it's been OK since then.

By "actuator" I meant the thing you can see in the photo above that converts the pull of the cable into a push on the push-rod.

Okey doke, i will grease my balls later then. :b
Got a feeling i may need to take a couple of mm of lever play away as well, as there may be a tad too much.
-
the very first week i had mine, stationary cold it was fine?..after a run when got hot it would click around that area, i too had the casing off ,cleaned all shit out and still it did it?...all i did was spray the actuator with copper grease worked it a few times and it went away!!..the spring looked very rusty and weak so replaced that too!!..only once since i did all that have i heard it again!...fazerider could be right it maybe that the innards need looking at?..but like he says them fkn screws are bstds to get out?...heat may help but they do round off easily!!...so be extra carefull doing it?
-
they do round off easily!!...so be extra carefull doing it
Yep I can back that up, I swear they are made out of play doh. Look at my picture----now look again at the bottom screw,bast*rd it would not move.So gave up. Im guesing that they are also fixed with a very strong threadlock as you woulnot want them coming out and falling onto your sprocket
Once as clean as you see it, that is a ballbaring that is loose in the middle once all the old grease is removed with a cocktail stick. I let a little bit of ACF-50 go down there and then re grease as much as I could around the ballbaring and abit underneath
-
Ho hum..........it has stopped doing it know. Honest. :rolleyes
The whole thing has been a complete mystery. But I think I'd go with Mr Gassitt's theory, and if it happens again, that is what I will work on.
Thanks for all you responses by the way
-
Mine hasn't stopped, it's clicking away like a good'un.
I adjusted the clutch lever play but that didn't make any difference.
I'll have it apart Saturday so i can give it all a proper clean and grease up. :\
-
Don't forget the lower nipple/tab theory - that's my first port of call should it happen again :rolleyes
-
It'll have to be Saturday now for tweaking my nipple and greasing my balls :lol
-
No theory Darrsi, this happened me at the 40000 mile mark and drove me to distraction. :'( Eventually I bought a low mileage second hand cover for €20 and then dismantled the original one to see what was causing it. The grease in the mechanism had dried out causing the bearing to make a cracking sound and the end of the lever pull when full pressure was on them. As a few previous post have said the foccing bolts holding the mechanism in place must be made of play doh. If the heads do not chew up the bolts shear. I found that heating the cover and drilling a hole in the bolts with a left hand drill bit before trying to undo them usually spins them out. Replace them with real bolts
I eventually devised a method of regreasing the mechanism without having to dismantle it.
Remove the rubber plug and remove the lock nut.
Remove the sprocket cover and clutch cable
Remove the mechanism spring and push the lever up as far it will go
Turn the cover over and using spray grease, I used a molybdenum disulfide spray grease.
Spray the grease into the bearing spiral. you can just see the bearings and the spiral.
Operate the mechanism a few time to allow the grease to run down into the bearings and repeat the whole thing 3 or 4 times. There is a seal in the moving part of the mechanism this is supposed to prevent grease getting out or water getting in :)
Put it all back together and all is well. You may need to leave it for a while for the grease to settle.
Prior to putting on the locknut remove the adjusting screw and spray a bit of grease in to the hole as there is a bearing in there also.
If that does not solve it then remove the mechanism, dismantle it and replace all 16 bearings and the 2 play doh bolts with real ones.

Well that is extremely helpful 'unfazed', thanks for that insight it's much appreciated, i couldn't find any info on what was inside the cover at all.
I've got a can of white grease, i may give it a go with that, otherwise i didn't realise there's loads of used sprocket covers for sale on Ebay. ;)

Cheers for that, i'll have a go at lubing it up tomorrow and make sure things are in order and if it doesn't work out then i'll look into getting another one.
My bike is in constant stop/start traffic so the chances are a used one will be better than mine anyway.
-
Unfazed well done and thank you for spending your time on taking and uploading the photos... brill !
Would it be possible to let us know what the screw size is as I dont think anyone is going the get them out in one peice and I would be handy to already have some new ones ready, And I would sugest that everyone also puts some thread loc on as you dont want then comming out and getting in your sprocket
-
Should have included the size. :rolleyes
Bolts they are M5 x 0.8 and are 9mm in length is is threaded the full length from the head of the bolt. The threaded hole on the sprocket cover is only 7.5mm deep and the mechanism is 2 mmm thick where the bolts are located. The best option is to use allen bolts as there is very little space. For those who have mangled the head of the bolts like I did a few times :eek , drill a 3 mm hole into the bolt with a left hand drill bit and if the bolt doe not spin out hammer a small torx bit into the hole while the bolt is still warm is the easiest way to undo them. :)

Don't s'pose you would know bearing size?
-
I have never heard of a left hand drill bit where do I get one of those
I see how it works - by cutting left the same way as undoing but I can just see myself drilling all the way through or snapping the drill and getting that stuck in there too!! (im a bit cack handed like that)
-
The diameter I got when I checked them was is 0.123 inches or 3.12 mm, there is probably a standard dimension close to that because when I took them into a bicycle shop and asked if they had any bearing like it he looked up a chart and had them in stock. They were the same size as the bearing in the rear bicycle sprockets used with the derailers
Left hand drill bits are available in most good tool shops and maybe Halfords. Use a variable speed drill with a reverse action and do not run the drill to fast. Take you time and apply pressure but do not force it and finally keep it straight. I used a normal black and decker battery operated drill with a fully charged battery. The top bolt is the most difficult due to its close proximity to the cover, just don't push the bit all the way into the chuck to give clearance from the cover edge.

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. :woot
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 ;)
-
Thats good news and good info on how to do it without trying to remove the two un-moveable screws. I think thats what you are saying

Yep, no need to touch them at all.
-
darrsi always said your a fkn ...genius!! :D ....doing mine t,morra!
-
As for the clutch cable after removing I put a short piece of tube (1inch) on the engine end and spray down brake cleaner whilst jiggling the inner cable up and down. Left it for a few hours with the odd jiggle here and there and also sprayed air down just to make sure that there was no brake cleaner left, and then filled up the attached tube with ACF-50 and let run down inside the cable. I think the tube was about 10 dia --that clear stuff

My clutch was absolutely luuuuuurvely this morning, it made such a massive difference lubing those bearings up. :D

Things are usually nicer with a bit of lubrication! ;)

I think it's something everyone should do as it's not difficult and it will get overlooked until it goes horrible like mine did.
It's not in the manual or anywhere other than this post i reckon, but it's so worth doing, it's a huge improvement.
Credit where credit's due though, it was 'unfazed' who suggested trying this way. ;)

...yep top marks for that unfazed!!...by the way did you replace the gasket or use silicoln?..bet thats why the half gaskets there?..to stop water etc getting in :rolleyes ...used black silicoln on mine!

No, all seemed rather pointless, it's a tight fit on the cover and it's not like it's a prime target for water.
Your chain will be spraying water and chain lube around inside it anyway, and if left out in the rain on the sidestand it won't get a soaking while it's leaning.

Glad to see it worked :thumbup I will write it up and put it in the manual download section. Mine was not rusty like Darrsi was, but I will include his cleaning method in the write and link it to this post. I would think the rust issue may be more from power washing the bike more than anything else as the inner section has a seal, whereas the rubber bung on the cover is not a perfect seal.
One less distraction to upset the enjoyment of riding the fazer :)

It wasn't surface rust, it was almost small flakes of rust, possibly caused by the clicking?
Which is why i wasn't too hopeful of it working, i was expecting to have to get another sprocket cover to be truthful.
-
Well thanks all - especially Mr Darssi. I must admit that I didn't expect the topic to raise much in the way of a response as I didn't think it was a common problem, But it just goes to show that you should never be afraid to ask. :lol Although my problem seemed to have stopped, I shall carry out the minor surgery as a precautionary measure.
Ride safe people

Its sort of like a nest of information bees on here...
You poke it a bit and suddenly the topic spawns out of control with hints and tips flying everywhere... plus the occasional hijack, great fun ^^

I'm in traffic all the time so use the clutch a lot, but it is an unusual one and it's great you kicked it off by highlighting the "clicking" noise.
I wouldn't be surprised if any make of bike could do with the same simple bit of TLC. :)

Does any other make use that system? I've not had a huge list of bikes before the Fazer, but they all used a simple lever on the clutch side rather than a complicated, hard to seal mechanism sited in an area that's going to get pelted with all manner of salt, grit and water if you use the bike in winter.
(If you flushed a load of rust out of yours, I'd be surprised if those ball bearings didn't need replacement rather than just fresh grease.)

That's still in the back of my mind, but the results so far are extremely promising that nothing needs to be changed! :)
The clutch is smoother than a monkeys bum :moon
