I'd either buy Dennis' kit or move your master cylinder up. Maybe look into a 7/8" bore cylinder too although I have a 4-1/3 ratio and have no problem pushing the pedal or in the braking action.

A couple of things, Glenn....you obviously DO know something about brake theory and physics. But, to be sure that Ian or anyone else is on the same page, there's BETTER mechanical advantage when the FOOT lever is longer, and/or the M/C rod actuating lever is SHORTER.
And yes, going with a SMALLER bore M/C will lessen the necessary pedal effort, but the pedal will need to stroke farther, and it's possible (when decreasing the bore of the M/C) to reach a point that there is not enough stroke in the M/C to supply the volume of fluid needed to fully apply the brakes. Just some things to be aware of. DD
