If you can catch an edge of the decal with your finger nail(s) and it gently peels off then apply some WD40 to any of the glue deposits on the tank and let it work. Then wipe off with with a soft cloth. Repeat till the gum comes loose. I used this method on my bike to remove the helmet safety sticker and dealer stickers on my tank and followed with a good soap bath and rinse and then applied a good wax to the tank. Decals on the windshield I used Goof Off after making sure it didn't harm the plexiglass.So, can I just peel off the orange warning stickers that are defacing my gas tank? (I suppose the federal government requires these on new bikes.) Will doing so damage paint? Should I use Goof Off on residue? Any tips or suggestions?
