You will probaly only need to raise your jet's one size in each carb. Maybe two sizes depending on what your running now.

CHEAPEST I FOUND THAT SHOWS A DIFFERENCE IN HP. AND STILL HAVE ALL THE PROTECTION FOR MUD RIDING WAS . REMOVE THE BAFFLE AND INSTALL A k&N AIR FILTER THAT FITS WHERE YOUR STOCK ONE DID AND DON'T DRILL NO HOLES IN YOUR AIR BOX.
YOU WILL BE ABLE TO BEET A STOCK RAPTOR EVERY TIME IF YOUR EQUAL IN WEIGHT AND RIDER ABILITIES ON A DRAG RACE. NOT BY MUCH BUT YOU WILL WIN. IT IS REALLY NOTICEABLE ON TRYING TO WHEELIE. THE FRONT WILL COME UP EASIER FOR SURE. bUT IT COMES UP EASY NOW BUT IT'S DEFFINETELY NOTICEABLE. BELIEVE ME.

IF YOU REALLY WANT MORE POWER GO WITH A 12 TOOTH FRONT SPROCKET AND JET IT AND PIPE IT. BUT YOU LOSE TOP END. MY FRIEND HAS THIS SET UP AND IT HAS MORE POWER ON LOW END THAN MINE. BUT I PREFER MY SETUP BETTER BECAUSE OF THE TOP END.
IT'S A MATTER OF PREF.

HE WINS IN A DRAG UNTIL I HIT FOURTH AND THEN IT'S OVER WITH

I don't think he was telling you to lose weight, I think he meant to take weight of the rappy, like removing things that aren't needed. As yamaha660r said go up a size, or if to lean, go two.
