If it's a decal, rubbing alcohol will help remove it. Rub the decal down with a soaked rag, let it set for a few minutes, then go at it with a plastic scraper (you can find one in the paint section of your local hardware store). Or, like Booger1 said, use a hair dryer and peel. Then used alcohol to remove any adhesive residue. I don't know if paint stripper will work if the graphic isn't actually painted on. I did have to use a little more stripper on the sections of frame where the factory decals were, but they still came off with just a rag.
