I finally got all the parts in and the bike is back on the road! It runs and rides great so far. However, my Speedo, Odometer, do not work and the ABS light is on. 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)

And make sure the brake assembly is riding over the square guide on the swingarm to stop it rotating when braking.
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??

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