There's an airhead parts supplier in Southside, Alabama, around the Anniston area, Motorrad Elektirk, the owner Rick Jones, has replacement spark plug wires for about $25 for the plain black variety, a bit pricey over the 'roll your own' type .
http://www.motoelekt.com/ignition.htm If the lighting relay was inoperative, the headlight wouldn't work at all, sounds like the light switch on the handle bar is bad if the head light only works in the momentary high beam position, I'll have to check a wiring diagram, I don't have one here at work .
My R65 gets all around usage, I'm a bit restricted on it's use, due to having collector insurance on it, can't ride it to work, but I work weekends and holidays, so I ride it on those occasions .
L. A. does that stand for Lower Alabama ?
