How do your rotors look? I have the rotors turned when I replace the pads (I thought it was standard procedure?) Maybe I wasted a little money but Our Honda's and Kawasaki both stop the same.
You can endo the bikes with two fingers and the rears lock up almost too easily.
Make sure to clean both the rotor and the pads, brake cleaner is great,
but I'm a cheapskate... Put some iso/rubbing alcohol in a small spray bottle. Use clean rags and wipe the pads and rotors down.
