All in all a couple of hours from go to woe with a minor amount of swearing thrown in.  Kuryakyn instructions will tell you to slide the master cylinder forward when you unbolt it, to enable easy access to the split and cotter pin holding the brake pedal on there.  Master cylinder moves sweet FA asper pic even with the crash bar unbolted.  Needed to unbolt either side here to get a bit more movement.  Got the split pin out easily with a pick tool, however getting the little sucker back in there wasn't as easy.  The headers were in the way and I wasn't about to take them off.  So basically it was a case of wriggle and jiggle and stuffing around until I finally got it to a point where I cold tap it in, was slightly misaligned due to the headers and the fact that the master cylinder was going nowhere in a hurry but only about half a mil out so took it easy and in it went.  

Bolted everything back together and am very happy with the outcome.  Much more relaxed position when riding and if you look at the pics it is now also about 30mm lower all round.  

Huge difference.  One small tip, make sure when you put the brake pedal cotter pin back in, the hole for the split pin is vertical, will save you some heartache trying to turn it around to put the split pin back in.  

 

My right leg must be an inch longer than yours.

Thank fuck !
