clutch basket torque setting please

Hi does anyone no the torque setting for the big nut that holds the clutch basket on the one with the locking tab washer , mine was only hand tight surely this cannot be right. I am changing the clutch as I am struggling to engage first gear on my 1972 st70 ,clutch is well worn . are there any other reasons why first would be so hard to engage ? Thanks

Hand tight is definately not correct. Don't know the correct torque for the nut, I tend to do that one by feel.
The washer -when in good shape and well folded- will keep the nut perfectly in place.

Check your gear forks as well as the selector mechanism / drum.
Is it a semi auto clutch? If so, make sure the clutch is in good shape, set it up correctly and test again...
Before you start tearing down the complete engine.

Cheers for the reply ,going to put a new clutch in and go from there.
