It is easy to do with most 4-strokes as they have DC. A voltage is more steady. With a zilla that uses AC, the voltage isn't as steady. If you do it, make sure you put a resister to keep any voltage surge down so it doesn't blow your LEDs. My dad and I are about to do this to his XP. Putting up LEDs behind the grill, then another as a brake light then some more in the cab. If done right, it looks great.
