this should solve your problem...
as your pads wear down, the pistons in your caliper must move further and further out... If they have not been cleaned in a while, the seals around the pistons can stick to the pistons, and will flex with the pistons as you use the brakes... everytime you let off the brakes, the seals "pull back" on the pistons and pull them away from the pads / rotor. This means, everytime you pull the lever, it has to move the piston out 1/16 or 1/8" before theres any contact piston to pad to rotor.
pull the caliper off, remove the pads, clean the pistons (pump them out a few squeezes with them off the rotor and then clean the dirty ring off them), then replace the pads, and dont pry the pistons back open... instead, with the pads in place, pump the lever untill you literally have to tap the caliper w/ pads OVER the brake rotor... i.e. the pads are dragging a bit. This way, when you hit your brakes, the pads are just barely touching already, and you have instant response, and when you let off, the come to "rest" still barely dragging the rotor (not enough to notice).
This is an old trick we do to our street and race bikes. It might be a bit tough to do on a supermoto where you have to install the inside pad after installing the caliper (like my YZ) but others should work easily.
It ends up giving you instant rock hard brakes, with little lever travel. Of course, this all only works if you've bled them well to start with.
