I just bought a blue YFZ and have had the same thoughts. My white with the blue graphics turned out better than I thought. (thanks Selector) It's a solid graphic (GYT-R makes them a solid piece that is the same size the plastic panel it goes on) so it may need trimmed so it doesn't look weird.
glad to hear the gyt-r has the clear backing. i had looked at it but wsn't sure if it did or not. the other flame one on the market is made by kandkatv.com and looks killer. i'm tossed between those two and the kissing girl one from skinindustries.com
