I just removed one last week.
I let it sit in the sun for 30 seconds. :lol:
Depending on your location a hair dryer may help.
Then I used my 2003 AMA Membership Card (knew it was good for something :lol: ) and got the corner of the decal lifted a little and then gently peeled it away. Then a little glue gone with a clean soft cloth, then wax and never know it was there. Take that Suzuki. :wink:
