Noise help please.

I've got a strange noise...i think

Right lads ,im lookin for suggestions .. I hope im not makin a mountain oot of a molehill here,but im sure the noise wasnt there previously

I hadnt been on my bike for a week or two,but went out for a short run today. Sittin at 40-50 mph there is a sort of constant vvvvvvvvv (dont laugh)

It sounds like road noise ,but when i slow down to below 30 its like v v v v v, it sounds as if it's something makin contact each turn of the wheel

It does it even when freewheeling with clutch in or engine off

It does sound like its coming from the front ,so i got home, bike on paddock stand ,and spun the front wheel ,the pads do seem to be biting slightly at a certain point ,but only very slightly.

Would a warped disc cause these symptoms,

Brake lever is fine when braking ,no pulsing

Also after riding/braking ,both discs are nearly cold ,they dont seem to be binding.

I spun the rear wheel to see if anything amiss, just a click click click click coming from the front sprocket ,much more so than the noise from the rear sprocket , i shone torch in,front sprocket looks fine although chain is nearly at max adjustment

Any ideas chaps

Stevie

How short was your run out? Did you do any heavy breaking? It could be where your pads have sat on the discs for a while and oxidized slightly and its that anomaly you hear as is spins past the pads. Normally this kind of noise dissappears after a couple of good pulls on the lever though. Did it change pitch on braking?

Hi ,
Just a short run,around 30 miles.
Trying to think...ehhh, nope it didnt change pitch when braking,only the frequency of it happening ,cos bike slowing down.
I didnt do any really heavy braking,just the normal,poss i should've tried that.

cheers

Hi mike,
i did think of that,but thought the noise would be constant with a wheel bearing

,although it does sound constant above 40 ish

Not really sure,ive never had one go on a bike

I did check when front of bike was raised ,i felt no free-play ,but didny want to push/pull to hard when bike was supported with trolleyjack under sump

Will double check tommorrow, cheers

I reckon Warby is right probably just the chain needs clean and lube, they make some funny noises when left for a while. Hope it is anyway a nice cheap fix

From bad to worse

Thought i'd check tyre pressures,front was sitting at 18 psi

,rather than 32 psi or so,.. havin said that last time i checked was around 8 weeks ago. Didnt expect to lose that amount of pressure ,checked tyre,no nails etc. Thinking maybe that low pressure is whats causing the noise ,but wont know till i ride it

Decided to check REAR tyre pressure , it wasnt registering a pressure on my gauge, I spun the wheel,and saw what i thought was a nail,so got the long-nosed pliers out, it turned out to be a sharp stone.

Fkn (excuse my french

) michelin pilot sport with less than 300 miles on it ,punctured right in the middle of the tyre (not in a groove )

Ive phoned 2 local motorcycle shops ,both need to see it,and charge Â£23 ish....... Â£17odd plus Â£6 odd if balancing is required

.........................or i could probably take it to a local car tyre fitter and get it done for a fiver

I think im goin to take it to one of the motorcycle places ........but,....what would you do ...nearly new tyre ,,,would you get it repaired, is it safe

Pissed aff completely noo

Yep if its not near the side wall I would plug it, the repairs are pretty much near perfect. If the tyre was down on tread then replace.
