ok , yeah no offence intended, i realise you may be frustrated by this issue and i didnt see your reply but thanks NEO, pictures can sometimes help though but not always

well you have the clutch operating arm which goes down into the case, around the shaft of the operating arm there is a groove, this groove is for a locating screw to keep the operator in position and stop it from rising up when the clutch is operated, also the operating shaft had a flat side towards the bottom half, this flat presses agains the pushrod and therefore moves the rod and opens the clutch plates against the tension of the springs this is how mine are and i guess yours will be similar....learn to post pictures!

Hmm if its been stood with water in the case i would advise a clutch stripdown, clean inspect and re-assemble, including the pushrod

yes there is a pushrod through one of thr gearbox shafts have you ever had this bike working? have you had the clutch off since?

its a bit confusing how one minute its suggested the arm may be seized...n the next it's moving 180 (ish) degrees? is it moving easily or some resistance as expected from the clutch springs?

I use a piece of wood!

sounds like its the white peaks area then any idea of the year of the bike?

welcome young un where in derbyshire?,

its the head you need to check keiran

well you will have the head off to change the gasket, all i'm saying is while its off check it, the chances are it will be fine but if it is warped you may soon get another leak

Cheers Alex Right...Come on out you lot!

shes a beaut Andy, enjoy

keiran check the head isnt warped using a straightedge

so you now need a regulator seana? these look very good value http://www.ebay.co.u...=item484266c37b They do a rectifier as well, http://www.ebay.co.uk/itm/New-6v-Rectifier-XT500-DT125-DT175-DT250-Yamaha-XT-500-QR353-/310355003799?pt=UK_Motorcycle_Parts&hash=item4842998997
