    1996 k1100rs spark plugs wire order

    So I have sort of a dumb question. How can one tell what order spark plugs wires go in on the 1996 k1100rs.(I didn't take this bike apart)

    Wires should be numbered near plug end. Cylinders are 1-4 from front to rear.

    Plug routing should be same as K100. Note wire #4 is longer than wires #2 and #3. It loops past #3 plug and goes back to #4 under the plug cover.

    Wonderful. Thank you. I'm guessing the #1 cylinder is the rear most and #4 is the front most ?

    NO !! ;-)

    On all 4 cylinders Brick-engines (K100,K1100, K1200), I am quite sure they have always kept the convention that #1 is front most and # 4 is rear.

    Front Coil: 1 & 4 plug
    Rear Coil: 2 & 3 plug

    Although it might not look as profesional, but technically you can reverse the HT plug wires at the coil from 1-4 or from 2-3 as it is a simple "batch ignition" (also called loss spark system). Each Coil will fire a pair of spark-plugs at same time (1-4 together and 2-3 separately).

    As published before in an earlier post, the length of each HT wire gives you a clue. For example: #3 HT wire will never be long enough to reach the front cylinder (but some will still fit at wrong place nonetheless...)

    Read the second sentence in my post over again.

    Coils are numbered on the paper/foil sticker on them. Each coil fires both plugs connected to it at the same time, so it's not critical which terminal of the correct coil you connect the plug wire to, but you do have to connect the wires to the correct coil (both the small primary wires and the plug wires).

    By firing both plugs at the same time, one plug is firing at the end of the compression stroke and the other is firing at the end of the exhaust stroke. It's called a "wasted" or "lost" spark system. https://en.m.wikipedia.org/wiki/Wasted_spark
