Hi again,does anyone have dual Mikuni 32mm carburettors set in Norton,what size are main jets etc?.

I would call Stan at http://rockypointcycle.com/ he sells the twin mikuni set up and can tell you how he has them jetted

I second the call to Stan. He sent me the wrong cable with my 34VM kit the first time and when I called him months later and told him a new correct cable was in my mailbox 3 days later!
