As a slight aside to this, I always remember the clutch being very heavy and clumsy to operate back in my old riding days when these bikes were "new". Quite a lot of it I felt (back then) was due to cable drag/friction and I tried heaps of times to get oil through the cables - with all the improvements in cable technology these days, is there a "best" supplier for cables to reduce the friction/drag inherent in cables eg Teflon linings etc, who also supplies the right lengths, including inner to outer??
