View Full Version : Chain noise
I'm getting a ticking noise from my front sprocket at low speed, and a sort of squeal from the same area at higher speed. The chain and sprockets are fairly new, and has always been kept oiled with a scottoiler. I can't detect any wheel misalignment although I'm not ruling this out. I can reproduce it on a paddock stand. The tick seems to occur with every link.
It's an SV650SK3.
Any ideas chaps? Should I check wheel alignment first?

Chain too tight?

Seems OK. Appeared a bit slack when I first heard the noise so I tightened it a bit, as per manual, on side stand. I spose I could!d slacken it off a bit and see if the tick goes away. The two noises I hear at different spends might not be related.

If front sprocket has 'nylon' insert, ie not solid steel, it can sometimes ride up on the nylon insert which can cause ticking sound , not sure if that explains the squeal? well known on Bandits.
Solid steel best.
The sprocket looks entirely normal. Just a star shaped lump of metal.

Does it make clicking noise with chain off?
Don't really want to say it, bearing behind sprocket?
Hoping I'm way off now!
Plan B - if its solid steel sprocket, wait for some of the more experience SV guys to wake up this morning and come up with simpler solution!
Not removed the chain yet. The squeal noise does sound like a bearing. The tick sounds like something to do with the chain.

Chain off, no noise at all. Also I can confirm that it's not related to chain tension or wheel alignment as I played around with both and it made no difference. The tick could be just normal chain noise - apparently some chains and sprockets are noisier than others. The squeal could also be just normal noise, perhaps a squeal isn't the best way to describe it. Maybe I've just 'tuned in' to these noises as I've been doing 30mph commutes lately instead of motorways. Also the chain and sprockets are quite new in terms of miles.
If it's anything bad I'm sure it'll get worse before anything catastrophic happens!

with chain off I would expect no noise as they would be no tension on the bearing to make it squeal, but if they is no wobble (play) in the bearing with chain off I would leave things as they are, just keep a eye & (ear?) on it so to speak.
Thanks for advice. What happens if the bearing fails?

THIS IS A GUESS ONLY:
more noise and worst case scenario chain locking up or snapping.
Never heard of this happening before it was obvious bearing wanting changing.
Just keep chain tension right and monitor the situation, could just be normal-ish.
Had this on my Street Triple and my R1 - in most cases, it's normal. Fingers crossed for you mate.
Thanks. I've checked everything I can think of to check so I can rest easy. Anything else is beyond my control.
Anyway went for a short hoon and everything seems OK. Still a shade noisy but I can't hear it over about 40mph. Simple solution - go faster!
I think it's probably normal noise and I'm just being paranoid. Just a bit noisier than the last set of chain and sprockets.

What you gotta bare in mind (I'm making assumptions on your maintenance here as 90% barely clean their chains) that a clean chain, and I'm talking spotless and new, doesn't have a fist full of gunk all over it like most normal chains...so weird noises will happen as it's metal on metal with little to nothing to dampen the sound. Here's a pic of how my Street Triple's chain spent it's life - never once had to adjust it:

It's not that clean but it's lubed with old engine oil via a scottoiler, so it's never had any proper chain lube or grease on there. Maybe I should try some.

Wurth dry lube. Honestly will never use anything else and I've used just about everything. Little to no fling, stays on there for ages, is a breeze to clean off.
Oh and I use Paraffin for cleaning with this wonderful little tool:

have you had the wheel off or had a tyre change recently.
an org member came to me with a very bad clicking sound which turned out to be a missing sprocket hub spacer which sits between the sprocket hub bearing and the back wheel bearing. the tyre fitter forgot to put it back in when they changed the rear tyre.
I read the thread Bibio. The rear tyre has been changed recently but the sprocket carrier is just slightly proud of the rear wheel, so I guess that's OK.

where did you get the tool..is scottoiler better the v system
Four wheels move the body. Two wheels move the soul.
life's to short for cleaning chains... lol

Get geared etc, I understand people not bothering to clean their chains - but it's a 5 minute job with this. Put it on, hook it in..plug in bottle with paraffin in it, squeeze and turn wheel. Repeat with lube.
Chain will stay sparkling and not need adjusting for eons.
