A dremmel would have been great... but I cut my mud flap off last night with just a house hold razor I had in the kitchen. Didn't matter that I messed up a couple times because it sands down nice a smooth. I left the signals and license plate on for now. I probably cut off about 6 or 7 inches. It's definitely nice to see more of the back tire. But now, from the side, it looks like the rear wheel needs to be extended a couple inches to make up for the extra room. I'll take care of that later though. As soon as I get some little LED's and a new mount for the license plate, I'm gonna pull out the razor again and cut the rest of the flap off, turn signals and all. When it's all said and done though, I CAN'T BELIEVE I TOOK A RAZOR TO MY HAYABUSA!!
