Trapped a Guinea Pig?

I have developed a bloody annoying squeak, definately drive train as the noise disappears with clutch in. At first I was picturing the front CCT but I am nearly almost sure that it is clutch related. After last ride cleaned adjusted and oiled the chain to eradicate that but I think it may be elsewhere. Any ideas? Pretty regular after you let the cutch out and accelerate but with the cans on you can no longer hear it after 4K RPM (gotta assume its still there).
So what do you gurus think?

Make sure you have good fitting earplugs?

I'll get my coat shall I?

Also getting coat.

Had a similar thing with a car once. Does it shudder at all as u pull away? In my case it runed out to be oil had gotten onto the clutch plates through a leaky seal on the shaft.

No it doesnt shudder mate.

Beamish,

When you say it disappears with the clutch in, do you mean pulling the clutch in while you're on the move

Yes mate, its more apparent at low speeds after pulling out into slow moving traffic, does not alter with application of the brakes but does dissappear with clutch pulled in.

Suspension Linkage??
Worth a look. Mine hardly ever squeaked when stationary but under load going along it would quite regularly:?

That's a good point Pete, and also known to need a regular greasing, especially if ridden all year around. Also check (if not already done so) rear wheel bearings, cush drive condition and that the chain is not too tight especially if you have any tight spots in it, you may find adjustment is too tight at a tight spot. If you have a paddock stand put the bike on that and spin the rear wheel by hand, see if that shows up anything,

Chris.

Cush drive is good and rear wheel bearings are ok, which area of the suspension is most likely to squeak mate, does sound to be more up the front? Thanks for info up to now

This bit

It's right on the bottom of your shocker and collects all the crap off the road. If it gets left too long it can do this

But at least it stops squeaking!

Right thanks Pete will take a closer look.

Good point Pete but how does that tie up with the clutch engaged/not engaged (unless a VERY soft suspension is having a pitch change effect?)

Simple.
A clutch will only squeak when letting the lever out unless it's slipping and I'm sure Beamish could diagnose that

. Once the bike is rolling with the clutch fully engaged it's highly unlikely to be the problem. It's more likely to be something under load when the engine is engaged so I'm thinking drive chain,suspension,bearings and brakes. Well bearings normally rumble or grind the chain will often have a rhythmical sound that coincides with its length, brakes can squeal dependant if they are on or off(not often for both unless there's no pad left

). So I reckon the next most likely candidate is the suspension. Oh, and I've had it before on mine

I'm not saying I'm right but Beamish is just after ideas here.
