The inner pannel stickers come right off. The tank stickers need a BLOWDRYER...not a heat gun (Unless you have skills). Glue residue can be removed with gas. It won't hurt the paint!!! How many times has gas splattered on your tank when fueling up?
Fairing stickers (yeah, I took ALL my stickers off even the graffix) peel right off, with slow, steady, even pressure after exposing to the sun. (no blowdryer, makes them to gummy).
The swingarm and frame stickers are a b.i.a.t.c.h. Use a flat, square razor(unless you have a Black powdercoat frame, then use a plastic putty knife)and skin off the plastic part leaving the glue, then use good old fashioned gas and a rag and remover the glue.
