Overly Helpful Kapinsky Volunteers to Rebuild Vintage Bosch Horn Assemblies

Long time tinkerer and member of the Vintage BMW Motorcycle Owners Club Ted Kapinsky announced this morning that he would be delighted to help anyone in need of restoring a vintage Bosch horn assembly.

When asked why he was being so helpful, Kapinsky shrugged his shoulders modestly and muttered, "One terminal is wired to +6 volts, the other to the horn button. When the button is pressed, it makes a connection to the ground, and electrons flow through the horn. By probing backwards in the circuit with my multimeter, I found that there was continuity—or zero resistance, as I prefer to call it—to the spring clip on the points. To inspect those properly, one has to count five turns when unscrewing the nut from the adjusting screw."

Fellow VBMWO member and acquaintance of Kapinsky Darryl Richman (#6285) quipped, "Ted isn't happy unless he's helping someone else, even if they don't really want his help and have told him to get lost. He thinks he's a f**king know-it-all, and he usually doesn't leave until he breaks something."

Although he never learned to ride a motorcycle himself, Ted is after the loudest and clearest vintage horn sound possible. Pictured here with his second favorite pipe, Kapinsky relaxes after reinstalling the six small screws that hold the cover and diaphragm to the horn body, at first only tightening them a couple turns, then the rest of the way until they're all in place, using an alternating pattern.
