*NOTE - this method works only on decals that are not "clear-coated" over. If your decals have been clear-coated over, do not use this method, it will not turn out pretty.
Step 1: Gather Your Tools.
TOOLS for disassembling the fairings. Take a look at how the fairings are attached to the frame. My Ninja's fairings are screwed and bolted, so all I needed were wrenches and a screwdriver.
1 bottle of Goo Gone
1 Exacto-type razor (I used a spare that came with a box cutter)
And an old rag/towel or paper towels for clean up.
Step 2: Disassemble.
I only needed a couple of different sized wrenches and a Philipshead screwdriver to remove the rear fairings. *You may need more or different tools so make sure to check before you start!*
Unscrew and unbolt until the fairings can be removed. Take note of what screws, etc., go where so when you begin reassembling it won't be a guessing game.
Step 3: Gather Up Parts.
Get out your Goo Gone, razor, and hairdryer.
I set my fairing on a towel so as not to dirty up the counter too much.
Step 4: Removing Decals (debadging).
*NOTE - Do not use an actual heat gun! It will fudge your paint and/or melt your fairing!*
If this does not work, use the Goo Gone to saturate the decal, then heat it at an edge. Use a razor to raise that edge up enough for you to pull it with your fingers. You will have to repeat this process several times, as the decal will tear into bits, so pray the other method works first.
Step 5: Remove Residue.
If the hairdryer method does work, then the fairing should be free of any residue, so pat yourself on the back b/c you saved yourself another 30 minutes of work. :)
