Limiter under the pedal? Like the accelerator?

Or do you need something more fancy and expensive? :D

I want to reduce the travel, may be altering the padel assembly or replacing the orignal master for a short fat one from a long thin one!

Re: subject should be clutch master replacement.

No takers on this?
How do you racers cope with the high clutch pedal?

You are sending mixed messages. What is it that you want?

If you want a short pedal travel, you will need to increase the bore size of the master or dercrease the size of the slave. Masters can be bored a size up and slaves can be sleeved down.
If you want to reduce total pedal travel and start lower than standard height, you will need to juggle specs on both so cylinders operate inside their correct stroke length.

As Mats has already suggested, if you want to limit travel beyond that which allows correct clutch operation, install a pedal limiting stop .

Bear in mind when changing ratios, you will alter pedal pressure and feel. You may also cause the slave cylinder to be overfilled and blow out the cups so a carefull limiting set up is required.

You got it(!) brother, I want a shorter pedal travel.
Is there master or slave cylinder replacement or modification that has been done?

Bruce,

Visit a clutch specialist machine shop. Get them to go the next cup size up on the master and one cup size down on the slave. Carefully monitor the installation after to prevent a blow out of the slave cylinder internals.

I would suggest doing this one stage at a time to gauge what is short enough for you.
