Sweet centurion decal! I haven't seen one like that before. I like that bike the way it is, but it's yours and you should do with it what you want, I think you'll enjoy it as a conversion. But since you asked here is my 2 cents.. I wouldn't paint it, I'd clean it up real nice though, make it nice and shiny. I think it would look awful with an orange chain and bartape, go with a regular chain, and since you got white wheels I would do white bartape, or cream-colored like those decals!\

Edit: KEEP THE TIRE SAVER ON!
