Having problems with 85 K100RT running not running on #1&4 cylinders. Very similar to what I read on what I believe it was Chocolate Frog's systems. I believe his problem was two bad injectors. I have fire to all spark plugs/cylinders. I can pull the #1 plug wires and no difference in running. Can pull 2 or 3 wires and it kills bike.
I have switched coils and no difference. Tried different plug wires-no difference. Pulled all the injectors, hooked to voltage and sprayed carb cleaner through them and verified they are opening and good stream discharging through them. I have checked each injector lead with a LED lamp and verified injectors are getting a signal. After reassembly took steposcope (bike running)and listen to each injector and could hear each clicking as if they were opening and closing. I have checked under tank frame ground, ignition unit and hall sensor connections. Each one were clean as a whistle and appeared no fault. I was wanting to trouble hall sensors but didn't quiet follow/understand logic from flow chart. Any suggestions would be greatly appreciated.
