Clutch free play changes when bike warmed up

[Larry Fine]

Could you tap the bore and screw in a set-screw to make it adjustable?

Okey doke. I measured the cavity in the clutch-lever bush and I made it 8mm. I packed the hole with a little Al-foil and the clutch action has returned to normal - hooray and thank you!!

I have ordered a new bush from Fowlers in Bristol, it should arrive in a day or two.

Once again, thanks for the input.

Glad you found the issue, a lot of times folks spend too much time and money over thinking things.
