Am I being paranoid? - Skippernick - 28-01-13
New rear tyre fitted last week and put the wheel back in all by myself, as far as I can tell its all gone in fine, no bits left chain slack is within tolerance etc.
Took it for a ride yesterday (90 mile) and there is a constant whirling/whine noise. Its not engine because it the same with clutch in etc. It correlates and changes with bike speed.
Can't remember if it was there before. Am i being paranoid or have i done something stupid?

wheel aligned correctly? don't rely on the marking on the swing arm.
pads rubbing?
Re: Am I being paranoid? - alexanderfitu - 28-01-13
Mine has had this noise since I have had it (which is only about 400 miles or so). I keep thinking its the tread pattern doing it, but i wonder if its the wheel out of balane, I have tried coasting in neutral with the engine off to hear more of the noise, and it does sound likes its coming from teh chain.
Your desciription sounds exactly like the way I would describe it.
Re: Am I being paranoid? - Skippernick - 28-01-13
Ok, so how do you check wheel alignment if you cant use the markings. I tried double checking using a ruler and measuring to the swing arm but it seemed that the wheel was naturally nearer to the left side of the swing arm. :o
Re: Am I being paranoid? - alexanderfitu - 28-01-13
bolt center distance to end of swingarm, if one side is closer than the other its not aligned!
Re: Am I being paranoid? - bigsteve - 28-01-13
I use a tyre depth gauge to check wheel alignment :rolleyes

If the wheel's misaligned it can cause a clunking sound as the chain tries to correct itself.
You sure the chain's not too tight?

Sorry which bolt? the chain tension bolts?

Theres no clunking sound. chain has about 40mm no more play in it.

Might be tyre noise
Re: Am I being paranoid? - fatboy - 29-01-13
Any noise when wheel is spun by hand,put on centre stand and run the wheel up to speed.listen for that noise.when i had new tyres fitted had same sort of noise.
Re: Am I being paranoid? - reillypadraig - 29-01-13
I have the same issue, but then again I did use a digital gauge but measured to the markings and slack is fine and chain is lubed, so markings on Swingarm can be slightly off??
Re: Am I being paranoid? - darrsi - 29-01-13
Generally speaking, the lines should be reasonably accurate, they're not there to mess with your head (or bike), but when the wheel's offset you should pretty well feel it being all wrong!
Heavy duty chains definitely cause a whirring noise, try lubing the chain and see if that makes a difference?
It's a difficult one to diagnose to be honest without us hearing it?
Re: Am I being paranoid? - His Dudeness - 29-01-13
if in doubt i'd just take it off again and check everything including the wheel bearings and go from there. shouldn't take more than 20 minutes
Re: Am I being paranoid? - red98 - 29-01-13
you can also check alingment using a straight length of timber or angle iron,rest it against both wheels the whole length of the bike and see if its touching both sides of both wheels......also take the chain guard off and look at the chain from the rear of the bike to see if its in-line with the sprocketÂ
Re: Am I being paranoid? - wezdavo - 29-01-13
I measure from the swingarm pivot bolt to the rear axle bolt to double check alignment..
Re: Am I being paranoid? - Skippernick - 29-01-13
Ok guys thanks a lot, lots of ideas i shall try and report back to you. SOunds like other people have this noise so at least its not unheard of.
Re: Am I being paranoid? - darrsi - 29-01-13
When i put a heavy duty chain on my bike when i first bought it the noise difference was very noticeable.
That noise, paired with the whiney gearbox was one of the main reasons i changed the end can to make it drown the sounds out.
Re: Am I being paranoid? - packie - 29-01-13
Chains can make noise as people pointed out. Have you a quite pipe and drive with your visor open? You hear a lot of things going on while riding with the above conditions. I can hear the cams whirring around underneath me ect. If you have a fairly load pipe and can hear stuff above that noise, then it would be a great cause for concern alright.
Re: Am I being paranoid? - alexanderfitu - 29-01-13
I can hear this over my pipe with the visor open, im pretty confident its the chain on mine as in engine off coasting it sounds very much chain like, I need to check the tension etc which I havent done yet.
