Front brakes overheating

I ride a 2009 YZ250 currently, but on every bike I've owned, I've had issues with front brakes overheating and fading. I've tried a few things to combat this, Braking oversized rotor, Steel braided brake line, some motul brake fluid with a very high boiling point (don't remember the name but it's a gray bottle with a red cap). These things have helped to some extent, but without fail I still manage to boil the fluid after a day of hard riding. I've also noticed that the new pads that came with my braking rotor- with about 5 rides on them, are changing colors like a pipe would when it overheats so I know they're getting hot too. I drag my front brake a bit in the turns, but I don't think I'll stop doing that at this point, so any suggestions on how to keep cool or am I doomed to melt brake pads forever? Thanks!
