Sorry for the Delay Kawaboy, took a break from this one. Only just started looking at it again in the last two weeks.
But I may have resolved the issue...
Turns out the Gap between the Hall Effect IC and its paired magnet was too far apart, for one of the three.
This issue has been really confusing because all the sensors checked out; based on the Kawasaki Manual.
Eventually I hooked up the Oscilloscope. With the Sensor plate removed from the engine cover. I ran the sensors past the trigger points on the rotor wheel.
Then I found that one sensor wasn't as sensitive as the others. After about a minute of spot the difference. I started thinking about the Gap and made a measurement.
The hall IC in question had about 1mm more than the others. After Bending it Back to the same amount as the other sensors it started triggering similarly to them.
Now I don't lose any trigger pulses to the Igniter when going above idle.
Next Time I get the bike on the Lift, I'll get a video of the Rotor slop.
