The problem with the SE is finding a location with enough space where you can mount a decent air horn.
I have to potential locations:
- above the rear cylinder behind the air box, where the SAS valve used to be (only if you removed the SAS system)
- on one of the cross bars of the raiddesigns rallye kit (only if you have the kit and enough spare room)
Both options still need evaluation if an air horn like the stebel nautilus will actually fit there.
The stock electrical horn sounds like a farting duck.
