I changed to front wheel on my 08 Ultra and now the abs light is on. I have replaced to bearing 2x with. An encoded bearing. I am getting code c1021. Am I missing something? I checked the sensor wires look good and it's plugged in..the only thing I'm wondering is: does the sensor need to be indexed into a certain position? I know I have it in the correct way just not sure if it needs to be rotated. I am at wits end ready to bring into dealer but don't want to loose the bike for a week.

Is the sensor bearing installed grey side out, orange side in ?
The sensor is directional, the wiring is routed up along the caliper.
The sensor is the spacer on that side, no other spacers used next to the sensor.
The stock 2008 ABS wheel hubs are specially machined to accommodate the ABS bearing with tone ring.
If the brake pads were spread to install the caliper and wheel the ABS pump module will need to be recalibrated on the shop Digital Tech computer.

I did have to put a small shim on the sensor side of the wheel...I also did spread the pads and replaced them...

Ok, time for a trip to the shop. That code c1021 means the ABS is getting zero signal from the sensor.
Was that wheel you bought specified for ABS ?

I can't say for sure if that spacer is the problem. The sensor and bearing tone ring need to be in close proximity to function. I don't remember seeing a spec for that dimension either.
Hopefully the mech that put the bearing in the wheel used the correct install tool and didn't just pound it in. That would damage the internal tone ring.

Looks better than I thought it would. Is it an 80/90 or 90/90? What brand is it? And how does it handle road snakes and grooves. I just switched to a 90/90 21 from the 80/90 and the ride is so much better now. No more following snakes or grooves.

It's a 120/70. It tracks great and I think it handles snakes fine almost like a stocker... I did notice the front wheel shutter at higher speeds is gone too!

That's always cool when people stand behind their work. Glad your back on the road.
