I saw that on a custom aqua Fat Boy. It had a special built motor, and tall gears. He used to like it when sport bikes lined up next to him, cause it really moved. It had aqua neon under the tank, basking the V-twin in an unearthly glow, and he had these lights on the plug wires, that zapped brightly as the plugs would fire. More neon under the frame made the street around the bike glow, and the V-twin made the pavement shake. It was quite an awesome sight at night. Even people who don't like that much flashy individual style would look at it, and go "Dayum"!
If its done right, it'd look great on a Viper. What the h*ll, you only live once!
