    If that was happening on my bike I'd probably order a new switch immediately. Unless there are dealers nearby (San Antonio, Lubbock or El Paso?) get on the horn to MaxBMW or Beemerboneyard or Chicago BMW and have one sent out is my best advice. One other thought---check Drake's website for a good used one (IIRC it's kbikeparts.com and he's in Seattle); if he does it'll be about a third of the cost new.

    Sorry that I can't help you much more than that but I don't know what else to recommend. If you were really in a bind I suppose you could Gerry-rig a momentary contact switch from Radio Shack after bypassing the BMW switch; that might work until you could get the proper replacement in place.

    Good luck and have fun on the RS! Jeff

    The headlight switch broke on my K75. I picked up a used switch cluster from my dealers junk bin for $20 and rebuilt it. Cleaned and lubed the contacts and it works like new. Brand new ones are rather expensive so you can save a lot, but you had better like spring loaded puzzles if you take one apart.

    Switchgear for either side show up regularly on eBay. And, as mentioned, if you're handy with wiring, it's a very simple single-pole momentary button. I fixed a sloppy run/stop switch on mine by disassembling, cleaning, and just a touch of bending to get tension where it had become loose.

    There are a couple (?) of small springs in that red & green switch assembly that will fly out if you're not careful.
