1999 Vintage Sport with the combination coil/switch mount that bolts onto the head studs. I've gone through an ignition switch (the old-school key switch barrel) on average about every two thousand miles. I've used multiple different brands, including a heavy-duty marine switch from NAPA. It's not the current that appears to be eating them, but rather the vibration. The innards of the switch literally rattle apart. End of March, I was 200 miles from home when the bike wouldn't turn off while stopping for fuel...replaced it when I got back home, and had to replace it again this afternoon. Any suggestions on a decent switch that will A) fit in the housing, and B) not just fall apart after a couple thousand miles? Short of getting a bulletproof switch that will fit in the factory mount, my next option would be to mount a toggle switch on the handlebar or frame, but can't seem to find a decent mount that won't look ghetto-rigged. Help would be much appreciated.
