I tore down my '85 K100RS a few months back for a complete going over. The parts are back from the painter now and I'm reassembling. Now that the fuel tank is back on, I've tried to restart it, without success. It turns over well, but no fire. I had the bike down to the bare frame, and had to reinstall the wiring loom and everything attached to it. I also took apart the bottom end of the motor and repaired the 6 rivet output shaft issue. I did not disturb the engine timing. I am wondering about the coils and firing order. I assume #1 cylinder is at the front. I'm not sure if I have the spark plug leads and coils set up correctly. Facing the coils on the left side of the bike, the coil on the left says 'Zyl 1 u. 4, schwartz/blau', and the one on the right says 'Zyl 2 u. 3, schwartz/rot'. I have the brown wire in the center position on both coils, the yellow/grn wire to the back (engine side) on both coils, the blue wire on the left coil and the red wire on the right coil. On the left coil, the #1 spark plug lead is to the outside, #4 to the inside. On the right coil #3 is to the outside, #2 to the inside. Does this seem right?
I have confirmed I have spark, and there is fuel pressure at the fuel rail. The plugs appear damp, but not soaked.
It ran before I took it apart. I did disturb the HES but believe it's in the right position.
Please, somebody throw me a bone. (That's Canadian for 'help')
