whats that clicking!

[White Noise]

recently i have been riding my bike and when ever i throttle off to slow down i get a strainge clicking coming from the middle/front of the bike. this is the only time i can hear it, not to sure if it does it when i accelerate as i can't hear it, also it does it with the front brake on and off. given the bike front a good going over for anything that might be causing it, came up with nadda!
thought that it could be head or wheel bearings but they seem fine, no notches in the head bearings. then tonight just found that when the clicking is there as i slow down. acceration fully off. no brakes! if i pull the clutch in the clicking goes away then comes back when i let the clutch out.
its really doing my nut as i can't figure it out.
can anyone help me out on this one?
Cheers?

Do you have floating discs?

Yea, on the front disc. Excessive play in the parts shown in the picture below can cause a clicking noise.

Only other thing i can think off are things like sprocket nuts, chain slack and swing arm bearings although these are more to the rear of the bike when the noise is coming from the front.

Stumped.

maybe the clutch is not working properly so its not holding back the revs properly (if tht makes any sense!)

kind of like the clutch is slipping abit??

Is it def the front of the bike? Because my bike has a very slack chain, and I noticed a rattle when coming to a stop or slowing down, and I found it out to be the chain hitting the swing arm I think. Check it out.

Hi

Difficult to say without knowing what you mean about the clicking noise.

I know that the thrust bearing on the Divvy can fail, but that mainly gives you massive engine breaking an a lousy gear change.

My first guess would be that some engine noise is being triggered by the engine braking. For example what you are hearing is a small amount of popping from the exhaust, maybe caused by leaking exhaust gaskets.

However, that is a pop rather than a click.

All the best

cheers for all the suggestions. i'm sure its from the front of the bike, its like an irregular clicking, i imagine it sounding like a notchy bearing, sticking and realising.
sorry to sound stupid by what it the thrust bearing? and what does it do? the gearbox does seem a little cluncky but not too sure if that is yamaha's for you!

try checking your camchain tensioner as it can stick (mine did) and cause a ticking noise on engine braking.

Hi

Yep, cam chain tensioner might be a possible one. Would explain the way it changes when the clutch is pulled.

The clutch thrust bearing on the Divvy sits behind the top hat shaped bit that is pulled when clutch cable is pulled. Basically it is the bearing that allows the non rotating clutch actuating mechanism to to pull rotating part of the clutch.

On the Divvy it is a radial roller bearing. Only about £5. Should be lubed with molybendium diasulphide grease (NOT engine oil as specified in the Haynes manual).

All the best

When my exhaust stud snapped but hadn't quite worked its way out it started making some /bad/ noises from the front of the engine. Could be a loose exhaust stud? A collar not making a good seal?

Now it's completely snapped and worked its way out, I sound like a tank.

Hi

When the you are getting engine braking, in effect you can have the rear wheel driving the engine. Just alters the loadings slightly.

All the best

cheers keith, didn't think about the loads being passed the other way to the engine and the clutch releasing that load.
gaz don't think that its anything to do with the exhaust due to the clutch having an effect on the clicking. if its not the tensioner think it maybe a expensive job! doh!

I am portuguese and i only know a bit of common english, do not know motorcycle vocabulary, anyway, i own a yamaha diversion from 93, my chain is a bigger one than the original with little rubber rings in it, so it doesnt usually make any noise.. until some time ago.. the sound you describe are exactly the same as mine.. when you slow down.. not allways the same.. like some loosen piece somewhere that you can ear sometimes.. ok. So now comes the most dificult part to explain in english.. the chain connects the wheel to the engine right? Looking at the chain, on the left side is the engine and the chain passes through an aluminium piece with about 6 screws, one of them is behind that part we put the foot on to change the gear. You must remove that part to remove the aluminium piece. In my bike, a coin did enter inside that aluminium part and made some damages.. There is a rounded piece that fits in the chain and is tighted to the engine.. the screw that used to tight that rounded piece loosed itself and the chain started to roll away from the engine day after day, making drastic marks on the outside aluminium piece.. thats the noise.. is the chain passing sometimes near the aluminium piece and that happens when you reduce speed with the gear on because the chain starts to stop the motor and for some reason try to go away.. please check this part inside the aluminium piece.. dont forget this part should be cleaned once in a while because every kind of stuff stays there, beeing transported by the chains rotation.
I hope this help you a bit.
