Clutch noise - Curvy.

Its when it in neutral not in gear. Its quite smooth between gears and okay going down

After long use, the aluminum fingers on the clutch basket wear where the steel tabs on the clutch plates hit them. This is a possibility. You've only got to pull off the clutch cover to look.

Just another thought, have you had to suddenly adjust the clutch recently?

Just a normal retweak after the chain was tightened. The adjuster on my cable is not a good guide as it vibrates in and out

That's what I was thinking, but if the nut works lose and the basket moves out towards the cover and the first thing you notice is the clutch lever goes slack.

I'm wondering if it's a lay shaft bearing, hence the gearbox rattles when not under load?

If it was worn fingers on the basket it rattles when the clutch is pulled in and the plates are free to move, not when it is released and the plates are compressed together.

the one at the lever end?

good thinking. i know he has crashed a few times so i wonder if he has given the gear lever a good whack..

well if the adjuster has been rattling then i would guess that it's every ride you are playing with it so you would not know if the bearing or nut is loose/burgred.

take the cable off and then the adjuster and give the housing a little squeeze with pliers then put all back together with a bit of non set glue (the stuff you get cards stuck to paper at petrol stations,, hint hint)
