Just an update on this issue. I stripped the engine completely and replace all transmission bearings and mains etc (peace of mind)
Measured up the clutch basket and it appeared out of shape and the area where it had been touching the casing was larger.
So i had the basket outer edge machined down untill the basket was true.
It has now been refitted and there is no noise and not touching the sides of the casing.
The strangest thing is if i removed all the bolts from the clutch cover and moved the cover around untill contact was made with the basket the clearance is quite considerable (even before machining) so techincally this is how much the basket must be moving around (about 2-3mm) in order to contact the casing.
I cannot get this kind of movement using a lever on the basket even by pulling the clutch in?
I will continue to use the bike and see what happens in the next few rides as if there is a problem with the basket it will only get worse.
