Thanks also Murray and Jim

Yes I guess there hadn't been too much science in this change over so it is biting me now, but it sounds like the issue can be overcome - I hope.

There was an evident mis-alignment between the slave and fork actuation but I had been working towards correcting this and it did slightly reduce pressure but nowhere near enough.

Will hopefully work out tomorrow what I need to achieve.

In terms of trying to do some belated maths, what measurements do I need and how do I make the assessment on the hydraulic advantage?

I am assuming length above and below master connection point to clutch pedal, cylinder size of master and slave - though I then don't know what to do with this data, length of clutch fork - should that length be from centre input shaft out to slave connection point? and do I need to know about thrust travel distance?

Feedback on the calculation techniques would be appreciated as I'm always happy to learn.

As I said early the one happy point for now is that McLeod said that a 3/4" master was sufficient for this application so I have one thing correct for sizing but as has been said, where it connects to the pedal is also important.

Anyway I look forward to further feedback.

Cheers

Steve
