No pic, but it's bolted to a piece of scrap flat stock that's bolted behind one of the four front peg mounting pipe bolts. (Or whatever they're called) You know - those two pipes that horizontally traverse the lower front of the engine. The horn is to the right side of the frame, about a foot or so off the ground, just inside the exhaust down pipe. It probably doesn't make a lot of difference, but I wanted the little horns to face forward for maximum effect.
A much easier way is to just mount the horn where the factory horn goes, like many folks do. I just didn't like it there for some odd reason. A length of black fuel line is lashed to the underside of the frame with wire ties to serve as a dry air inlet.
