Nuts, chains and sprockets.

[darrsi]

Just got the nut and tab washer, obviously it's the 12mm one but as in the pic above of the old 9mm one, there's a shoulder of about 3mm which i assume locates on the plastic bit on the original Yam sprocket, to quieten things down i believe?
So, my question to those of you who have had to replace the old nut with the new one, what do you consider the best torque setting, after of course adding threadlock to the shaft threads?
I would rather take advice from someone who has done this than rely on the Haynes book of lies, to be honest.

From memory i think the old one was 70Nm and the new one was a suggested 90Nm, but i personally had mine torqued at 80Nm.
