Have you pictures of said decals? Are they available from the ROG store? If they're cool I might need someI debadged just because i don't like the look of chromed plastic badges, they seem a bit gaudy to me. Then after afew weeks I decided the tank was too large and bare so I got "rogue" decals and pinstripe made that matched my bike.
Then a couple weeks ago when I broke my bike I layed it on its side on some plywood to work on it and got called away. Next morning I found I had leaked a bit of gas and it ate a decal. Luckily I have some extras.
I tried it-- it didn't loosen it up at all. That was some nasty stuff. I suppose it's been cooking on there since 2006. There's a very faint darker area where the badges were (expected). I hope they fade out soon.WD40 is great for adhesive removal and wont harm the finish.
