BEEP !! BEEP !!,God I love those little "slim Line" horn tanks, I have 2 bikes with them a 26 inch and a 24 inch American w/the slim Line tanks and people freak that they still work. TIP: after thouroughly cleaning the horn mechanism and contacts, shoot it with a little of that blue Permatex spray that inhibits corrosion on car batteries. Since i did this, my horns that were cleaned in 2002, with the same "D" cell batteries, still honk away, I'll swear by that stuff for all battery powered contacts.
