Without actually seeing it, best guess is the float needle is stuffed.
There is nothing to be gained with after market pads. The Suzuki HH pads arguably offer the best all round performance (including feel) for the average rider.
Perhaps the one area where they lack is outright braking performance and the only real fix for that is a larger rotor. The best improvement that can be made to the brakes after ensuring that everything is in good shape (ie clean, greased wheel pistons and sliders and fresh well bled fluid) without spending large amounts of money is a braided line - especially so if the bike is more than a couple of years old.
Mine has a 320mm EBC rotor (+ larger 240mm rear with an SM caliper bracket), Suzuki pads, Venhill braided lines and the calipers are stripped and cleaned annually. They have power and feel, but it cost a little more than pocket change and I do need to be mindful of the rotor diameter on rough ground.
The bars can be raised 50-60mm before cable lengths become an issue.
