Modern Vespa

The project reports on stebel fitting rock. Buglake's is a good place to start. Good luck.

The Stebel Nautilus Compact's horn and compressor can be separated and connected by a flexible tube. If I were starting over, I'd do it that way because space is so darn tight inside the fairing (don't forget the suspension travel). Also the installer must wire a separate circuit and relay; the OEM horn wiring isn't set up to power a compressor.

Hadn't realized that and good to know. I just got my horn in the mail and hope to start install - along with numerous other mods - next time I find a couple of free days... or maybe just another all-nighter. I'll take a look at the horn tonight and see what is involved in breaking it (!!) apart, and even if I really need to. Thanks for the info!

Anybody have any idea on how i can put my train horn on my mp3,when i sold my semi tractor i took the thing off and it is just laying in the shed. It is a 3horn thing that did come off a freight locomotive had fun with it when it was on the truck. You want loud that thing is.

First you need to mount an air compressor in place of a top case.

The compressor would have to be about the same size as my mp3 or pull a trailer with it mounted on it and a long electrical cord to power it

Or use a CO2 tank.

Just to give you an idea how much air that thing takes on my semi tractor i had 3 air tanks that carried 110psi 30seconds would empty out the tank.

30 seconds and every one in the general vicinity is deaf.

My neighbor had one. I know what you mean.

A guy worked on my truck and set it off inside in a buiding couldnt hear for awhile, had a an other driver stop at a train track because he thought a train was coming I paid for that one

Reminds me of an accident on a fire truck in Germantown, TN. The driver used the horn too much and didn't have enough air left for his brakes and couldn't make a turn. The town modified their other trucks to split the air system between horn and brakes.
