Given the situation some of us are in, trying to find obsolete parts, I'm wondering if anyone has tried drilling out the rivets on a moped horn, dismantling it, cleaning it, and then riveting it back together? If these were available at WalMart for $5, then the answer would be obvious! I have a 77 Smily that hasn't been on the road since 94 or so. It's been down cellar collecting dust. it's getting a new plate tomorrow, and will actually get used as a pleasant diversion from my '77 CB750, but the horn only works once in a while, and then only a meek little rattle. I'd be willing to take this one apart & fix it, if anyone could give me some ideas. Thanks.
