Hi Eric,
This type of mechanism has indeed been around for a long time. It dramatically reduces the force required to lift the clutch as it makes use of the reaction force of the cable outer that is lost on the gearbox case in the standard mechanism. I produce the mechanism shown below, this is to a design drawn up by Roger Moss. He has used this on his racer for many years.
It is not a direct fit, as there are some small modifications required to the back of the case, requiring the case to be out of the bike. The standard bronze quick thread release is very prone to wear, being open to any road grit. This improved type overcomes that problem also.
