Just had a look at my abs sensor and think that if you were to assemble the brake assembly with some grit in between the brake assembly and the wheel bearing that could space out the sensor away from the slotted ring just enough to stop it from registering the slots, my gap is 0.04 mm. maybe just worth taking it apart and inspect the mating surfaces, just a thought.
And make sure the brake assembly is riding over the square guide on the swingarm to stop it rotating when braking.

The cluster does a full sweep and everything else is working including tach.
As far as I can tell the ABS sensor and wheel speed sensor on the rear right of the bike are one in the same. That was undamaged in the crash, but the wheel adjustment bracket was. I had to take the axel out to replace it, but I meticulously put it back to match the other side. There is no brake drag from what I can tell, either. Everything is pointing to it being straight. I checked the connections before assembling the headlight and meter and the I found the plug where the ABS sensor terminates and it is plugged in and intact.
I was doing some reading and found that there might be a gap spec that could be the reason for the light and speedo/odo not working. But I'm not sure since it was for a different bike, and just a theory.
Everywhere says the meter is plug and play, so I'm wondering where I went wrong or if I missed something. The dealership quoted me $70 just to diagnose so I'm hoping for some ideas that I can try at home before I go that route.
It sounds like the problem is simply the air gap between the speed sensor and the pulser ring with all the slots is incorrect or uneven. This ring needs to run perfectly true. Any high/low spot can stop it from working. Gap should be .002" - .005", thinner than a credit card.
Joe, sorry, but my service manual says:
Wheel speed sensor air gap : Standard: 0.4 - 1.2 mm (0.02 - 0.05 in)

Is that measured clearance or typo error?.....it would not be enough room to swell up when hot, or dirty.....
...or you meant 0.4 mm or 0.04" ?
OR I am wrong again??

Thanks peter, you're right, it was late and the measured gap is indeed 0,4 mm.
Here are two pictures, one with the feeler gauge under the sensor and the other one showing the feeler gauge size.
Apologize for the confusion and thanks for picking this up, very much appreciated as usual.

My specs are wrong, went from memory. PB and Max are correct.
