Update today: clutch issues? More videos

http://youtu.be/x418HWd-PPY

Had my cam chain done due a rattle.
Seemed obvious as the tensioner was almost near the end.
Had a service at the same time all done by a specialist local to me.
The bike still taps, I've been told it definitely isn't the chain, it's a more frontal noise low down.

Hot or cold makes no odds.
It's not that bad on idle, anything more and you can hear it, hopefully it can be heard In the video link.
Anyone had anything similar at all?

Thanks

**excuse the original thread being on an attached picture. This stupid ipad wouldn't submit it and I kept re typing and it wouldn't work so I've posted that, and edited this post to say almost the same thing now. I love technology.

Can't watch your youtube vid. It is private.

Paulfzs · « **Reply #2 on:** 17 March 2015, 02:13:11 pm »

as above private video.

frontal tick? check header pipes.

davidkent · « **Reply #3 on:** 17 March 2015, 03:02:20 pm »

I'll look into that now re video.

Check down pipes?

I did tighten the nuts up a bit but don't really know what to check for?

Cheers

that sounds like bearings to me :/

davidkent · « **Reply #6 on:** 17 March 2015, 03:06:52 pm »

Bearings?

davidkent · « **Reply #7 on:** 17 March 2015, 03:07:24 pm »

The noise started suddenly also, no gentle happening. Just happened one day I started it and it seemed rattly like this

Paulfzs · « **Reply #8 on:** 17 March 2015, 03:10:56 pm »

cam chain changed and rattling still, im no mechanic but it sounds bad, the cam chain issue is usually a clicking at tickover then pretty much goes when the throttles open.

davidkent · « **Reply #9 on:** 17 March 2015, 03:12:09 pm »

Probably never needed a chain then lol though it was nearing the end of its adjustment. Bummer. Well thats done now, but hopefully this isn't major even though it sounds tobe lol

Paulfzs · « **Reply #10 on:** 17 March 2015, 03:15:39 pm »

could be anything, it may go away.

im sure someone with more knowledge will post soon

Is it worse or better than before cam chain service?
Cam chain fitted properly on camshaft gears?
Cam chain length correct?
Has the tensioner been cleaned and reset?
Anything dropped inside the crankcase?
If everything seems ok, maybe you should give it a few redlines and see if it settles.

davidkent · « **Reply #12 on:** 17 March 2015, 05:27:56 pm »

It's no worse or no better. No different really.
I assumed it was the chain needing doing, and that was the noise.
Clearly I was wrong.
I didn't do the job but a specialist did.
He didn't encounter any problems or nothing that he mentioned.

I'd imagine the length is right, though how do you know?
How could I even tell this now it's in?

I've cleaned and reset the tensioner a few times myself personally.
I'd like to think he did it again while he had it out. But even if he hasn't, I did it 100 odd miles previous anyway

I redline it regularly, it hasn't settled, and didn't settle when I last rode the bike last summer, before the chain was done only last week

Thanks

How many miles on the clock?

davidkent · « **Reply #14 on:** 17 March 2015, 05:32:11 pm »

28720 as of today

Any change when clutch is engaged/disengaged?

davidkent · « **Reply #16 on:** 17 March 2015, 06:53:23 pm »

No, clutch makes no odds.

Originally I thought perhaps related with having the clutch and gubbins apart a while ago, though I'm pretty sure I put it all together fine.

When I take the oil cap off with the bike running I can't make out if the noise gets louder or not, it seems to if I'm leaning over the bike and am above, but if knelt next to it I'm not so sure.

A screwdriver to the engine (in various places) and to the ear may help you track down where it's coming from.

Loose valve? A pump?

It sounds very regular, where as I thought cam chain tends to be kind of occasional tick mostly when coming off the revs or on idle.

I know its a long shot..
have you fitted an aftermarket down pipe?
I had one on my thundercat and that made a tapping noise which wouldn't go away.
it turned out that the shock waves or what ever was hitting the thin walled s/steel pipes making it sound like a tapping noise.
had that bike 4 years after the tapping noise was notice.
and the bike is still on the road.

davidkent · « **Reply #19 on:** 18 March 2015, 12:37:49 pm »

Well Trybthe screwdriver later

It has stainless downpipes which were on it when I bought it however it didn't make the noise for the first year of ownership :/

davidkent · « **Reply #20 on:** 18 March 2015, 03:25:15 pm »

Tried this.

Clutch area
taken clutch out

It's all to shit and rattles.

What order does it all go in the basket?

Should the plates move when the cover is torqued up (8nm)?

See videos to describe more but I must have it in wrong now as I can't use the clutch

Had a cheeky start with the cover off and the noise is almost certainly in there...

There's the clutch rod, a ball bearing then the end centre plug cap type thing then all the friction plates and cover.
As above what order should they be in and why do they move? Am I missing something perhaps explaining the noise?

Looks like you've re-assembled the clutch with the pressure plate oriented wrong. It's fussy about which set of holes the screws line up with, if you take it off and relocate it 60º or 120º it should seat properly and you'll feel it clamping against the plates.
The bad news is tightening up the screws with it in the wrong position fractures the bottom of the wells the springs live in, so you'll need to buy a new pressure plate.

davidkent · « **Reply #22 on:** 18 March 2015, 04:41:00 pm »

Jesus Christ. Odd though and still doesn't explain the rattle which seems to be coming from there :/

davidkent · « **Reply #23 on:** 18 March 2015, 05:11:10 pm »

Clutch back together lol
There is a noise that does go when the clutch is pulled in, so I've cable tied the clutch in so I don't get confused.

When my chain snapped about 18 months ago, I ended up having to replace the water pump as it was split by the chain hitting it.

I used a second hand part.

It's pretty noisy down there, is this possibly signs of a water pump issue?

Try a stethoscope see if u can locate the noise at it worst ,you can pick one up on eBay I use one on my bike , you can get close to the noise will give you a clue
