I can't see if the ball is missing on yours Craig ?,
This is T.T.s mod' , I find the balance on the springs is more easy with the mod' ,
The old type can change with the heat,
Mine was Perfect after the mod', Till I had done a few miles ,
They were old plates which I just wiped,
Then the oil got to the plates and made gear selection not SO good, But still good,
It always been a nice clutch !,
So next time it's in bits, I will weld a cover round the drum ,
To keep excess oil off the plates.
Cheers Bill.
I think I had to bore out the centre hole in the plate a Nats !, To take T.T. s Mod.
