It's been mentioned before. The pads on your bike really suck. If you replace them with quality stuff they will improve 100%. A plug-&-play swap are the pads from a KTM XS65 I believe. Well it's a KTM I remember that much. After you replace the pads remove the crap brake fluid and add some good stuff and take your time and bleed the brakes correctly and you'll have a worlds better braking set-up. Now if it's a track set-up your looking at one caliper ain't going to get it done no matter what you do.
These
photo's show you a little of what you can do with time, cussing, and a few bruised knuckles
