I currently have YZF750 six pots on my FJ1200. They to have a tendency to
give a soft brake (make that excessive travel on the first application),
compared with my Ace one piece calipers.
You can actually see the pistons being drawn back by the action of the seals
and hence ready for the next 'soft lever' application.
I've found that when servicing the YZF six pots the pistons are easily
pushed back in by hand, therefore if the seals grab the piston slightly,
they easily drag them back. I found by pumping the pistons out as far as you
dare, cleaning them thoroughly and greasing them with your favourite potion
(I use PTFE spray grease), they tend to slide though the seals without being
retracted so much.
This is on the YZF750 six pot calipers and may not apply to the GTS, but it
might be worth a try.
