Funny noises - Another Pitstop post from me *sighs*

[Foxy Stoat seeks Pig]

So I've noticed on my last few rides that there is a kind of whirring grinding noise when I'm coasting at slow speed, in traffic or coming to a stop. I cant pin point exactly where its coming from. I'm very paranoid about any kind of noise/creak/groan after my last breakdown.

Its difficult to explain the noise, I think to describe it a 'grinding' noise is too harsh. When I apply revs it goes,when I roll off throttle it comes back but of course higher revs and the noise would be drowned out anyway.

As I said could be my paranoia and worry setting in. Noisy when coasting with no revs.

Any ideas from my very vague description?

Thanks all.

I had a simular thing,best description was felt like a seized chain link but was gearbox input shaft bearing gave up and broke the cage.

Took clutch cover gasket off and could move it 1/4" up and down

Was it a big job to fix?

Split engine cases, replaced all bearings

Checked brake pads aren't worn / sticking?

I Haven't but I'm pretty sure it's not brakes. When I was spinning wheel yesterday when cleaning the chain I could hear the noise. Sounding like from the front sprocket area but now sure. I have checked the nut is still as it should be just in case.

have you adjusted the chain recently?

I don't know how so that would be a no from me worth looking into?

[Stu]

If you had adjusted it recently and the noise had started I would have said to check the tension as it could have been too tight and causing pressure on the output bearing

When I set off this morning the noise had gone. By the time I was in town (about 15 mins ride) and the bike had warmed up I could hear it but I have to really concentrate hard on it to hear it.

Any revs or traffic noise and I cant hear it but it is there because when I pull into the car park and its quiet that’s when I can hear it most.

I may be overly worried of course or maybe it should be like that. My CG had a kind of a groan when of the revs but I just carried on regardless.

Appreciate all your advice so far

As you hear the noise in two different circumstances: 1. Engine off, spinning the back wheel and 2. Engine on but stationary (in a car park), then I would suggest looking at your clutch. It could have 'warped' plates, be too slack or, the shaft bearing is shot.
