    '85 K100RS Two wires behind speedo

    Just taking things apart, look see, '85 K100RS, behind speedo two wires labeled Kabelfertigung, red and white, and brown. Look like they powered something up, don't have schematic. Thanx if you know.

    898,

    Please try to remember to include the year and model in the title (I added that for you).

    When you say "behind the speedo", do you mean inside the cluster or outside?
    Are there any connectors on the wire ends? What kind? Pictures would definitely help.

    Kabelfertigung means cable manufacturing.

    The only red/white wire that is in that area that I'm aware of is the power wire for the clock and that wire should be plugged into one of the two long connectors on the back of the cluster. Any brown wire is a ground. Does your clock work?

    Think I figured it out, there's a gray/wht wire connected to the same spade, probably the parking lamp, which means the red/wht wire was just an accessory hook up for something. I'll just remove for now. Thanx.

    The terminals on the end of the wires appear to be round "banana plug" style plugs. As far as I know, all the stock factory terminals were flat "spade" type connectors.

    If it's hooked to the parking light, it probably IS for an aftermarket or factory optional switched source like powering the relay for driving lights. Or it could be used for switched power for very low current items like a GPS.

    Just tape it off and leave it for future use. But, only use it to switch relays or for low draw electronics. Don't use it to directly power anything with any significant load.

    Anybody hook up a vacuum gauge to K100 lately? I did last night and it bounced all over the place. Have to wrap me head around that for a while. Idles good, pulls good, can make it back fire if I rack the throttle up and down, and it burbles real nice whenever backing off. Guess it's like most bricks, a few glitches. Got all winter to have a look see. Just mounted new rear tire today, almost had a stroke, haven't mounted a tire for some time. However, bricks are very kool bikes. For an old airhead rider, gotta learn some new habits. FWIW, This bike goes like a silver arrow. DSC_0896.jpg

    The needle on a vacuum gauge will "bounce all over the place" if it's not an adequately dampened gauge.
    A dampened gauge has a tiny restrictor in it so that it does not show rapid changes in the vacuum signal. Since a Kbikes vacuum ports each only read a single cylinder, the vacuum signal varies wildly between valve overlap and pure intake stroke.

    A dampened gauge will show a constant reading. Yours is not adequately dampened. A plug in the hose with a hole SMALLER than .030" should do it.
