I found a mcn article online about motorbike noises and it says that a squawk is most likely to be the clutch going. This sounds plausible as I never really thought this noise was from wheels, bearings or forks etc.
Any thoughts on the clutch theory and is it an easy job?

You may be thinking a bit too far ahead.
First thing i would do would be to properly adjust the clutch cable from the bottom as well as the top, and see if that makes any difference.
I'm guessing you have the correct amount of oil in the sump as well, and it is within the recommended mileage range, or does it need changing at all?
I've never heard of a clutch causing a squawking noise either to be honest.

Need to check the clutch items you mention. All new for me. Engine oil is clutch oil right? If so then all is good. In range and right level.
If you say clutch doesn't normally cause squawk then it might be another red herring. I thought a slightly faulty clutch would make it safe to ride until symptoms become more apparent or obvious. I have checked brakes and bearings so think it will be safe to ride anyway.
Was also wondering if the noise could be coming from the air side. Maybe carbs, head gasket, loose plugs....
I will see how to check and adjust the clutch cable next. If nothing else I am learning about my bike.
Bike would run terribly if there was an issue with the things you mentioned.
Engine oil level needs to be checked on the centre stand AFTER the engine has been running for 30-60 seconds so it's spread around the sump.
It will then take anout 90 seconds to settle in the sump window.....that is when you check the level.
So i would double check that to make sure it isn't low, a lot of people mistakenly check the level when the bike is cold, which is incorrect and will give a false reading.

I'd clean all that gunk out from the sprocket and sprocket cover. You said you thought your squawk was coming form the front sprocket area at one point. Maybe your noise has something to do with all that build up. The clutch actuator is in the sprocket cover. When you pull the clutch lever the actuator moves out and pushes against the clutch push rod. The clutch push rod is the part that's sticking out on the left of the front sprocket. All that should be clean.

Could a bit too much oil cause this?
It can cause issues, but not the noise you’re describing.
Have a good read of this though, worth doing: http://foc-u.co.uk/index.php/topic,10124...#msg105459

This is a weird problem. We've not got a lot of information to go on. All we know is the bike has 31K on it and there's a squawk happening sometimes when he's slowing and he's not too sure where it's coming from.
So far he's found a very slack chain and he's tightened that and the squawk is still there. He's checked his chain and sprockets and his wheel bearings and sprocket carrier bearings and they're fine.

Does the frequency of her squawk change with speed? Does she squawk on acceleration or deceleration? We're going to need more information to solve this one. Maybe some pictures and a video of the squawk :rollin :lol
added a smidgeon of oil that I don't think was necessary
Removed the front wheel, checked the bearings to be OK and added a bit of grease.
I guess my lesson learned now when she is squawking is to check the safety stuff by a process of elimination. i.e. brakes, chain, wheel bearings, drive bearings and add a wee bit of grease. I did not think that kind of noise would come from the wheel.
Hey ho thanks for all the tips, hi-jacks and connotations :rollin. Am a bit handier with the bike now
Have been watching this and it has been good reading all ideas on the Squawking noise. So ive had just a wee thought. Front wheel off. Was the front wheel torqued up too much ? If the spacer on axle had a rounded face - inside face - then your front wheel has been torqued up to much and it would make a noise. The wee bit of grease always helps.
Added a wee bit of oil. Has your engine had right oil level ? All engines make some sort of noise under or on acceleration. No two engines are the same. When your doing an oil change you will notice a change in engine noise as fresh oil in there helps keep them sweet. Also different oil's will change the pitch of your engine.
Due to peoples different ideas of describing sounds, have a look on YouTube at cam chain noise/ticking, seeing as it's not been mentioned.
Bit of a wild guess but worth ruling out just in case.
Terribly difficult to pinpoint a noise when the bike needs to be moving.
I had a strange buzzing noise for months that has now disappeared but i still have no clue whatever caused it?

I used to get this.. could hear it around 30mph or so... it went after I had tyres fitted and the fitted gave the speedo drive in the wheel a thin smear of grease.
I noticed something yesterday that could well be the culprit of the mystery noise on my bike, and maybe a few others too.
I just happened to glance down at the front mudguard extender and couldn't help but think it was hugging the tyre a bit closer than i remember when it was fitted.
My one is not glued on, i've used the 3 plastic rivets it came with and drilled holes through the standard mudguard to fix it on properly.
On closer inspection though i could see that the centre bottom part of the extender has a little upside down 'V' shape in it where the tyre has rubbed on it and worn through it.
It had a good 6 or 7mm gap when stationary, but i reckon that a combination of bike vibration, plus the tyre movement, sucks the extender towards the tyre just enough for it to skim it and make the circular grating noise that's been driving me potty for months now.
It would also explain the reason why when i pull the clutch in the noise will stop because i'm cutting out the bike vibrations.
Don't know if it can be moved back slightly, but it would seem that over time the extender has sort of curled itself towards the tyre just enough to make this irritating grinding noise.
Problem solved.....for my bike anyway. :think
