I'm new to bricks. But I'm learning fast. But I need some guidance.
I've been handed a 1989 K100LT to try and sort out. It's only running on cylinders 2 and 3. With my temperature gun I can see that 1&4 don't warm up. But 2&3 do.
First thing I did is pull the plugs and check for sparks. They are all sparking.
I removed the injector rail and turned the engine. They are all squirting.
I swapped the coils around and the cylinder for 1-4 happily runs cylinder 2-3. So I think the coils are fine.
I have replaced the HT leads and plugs also.
If I unplug the coil for 1-4 when the bike is running, it makes no difference. But if I unplug the coil for 2-3, the bike completely dies.
So, I'm thinking the Hall effect sensors ?? From wiring diagrams, I see there are two. Are the two sensors one for each coil ??
Would the injectors fire if one was faulty ? I would assume the HES also fire the injectors.
In past experiences from faulty Hall effect, I would think I would get NO SPARK at all..
Can anyone point me in the right direction ?
