Oh man. That stinks. Hopefully they'll come off with a little alcohol or "goo gone". I've used the goo gone stuff, by the way, it doesn't seem any more effective than plain old rubbing alcohol. It just costs more money. Neither worked well on the old AAA stickers stuck to the bumper of my car.
Glad to know there's a fellow Shogun 500 rider out there. I have yet to see another bike like mine in person.
