SPEED SENSOR TEST
With the key on probe the bike harness red wire for 12 volts.
Probe the bike harness black wire for continuity to ground.
Using the proper equipment, raise the rear tire.
While spinning the rear tire put the Black probe to ground Red probe to green signal wire.
You should see between above 0 but less than 6 volts.
If no voltage registers, replace the speed sensor.

1. Disconnect the cam sensor from the ignition module.
2. Take out your trusty multimeter and set it to the RX1 scale.
3. Now while touching the sensor backing plate with the negative meter lead touch the positive meter lead on each of the three wires of the sensor connector (red, black, & green). If you get continuity from the backing plate to any of them the sensor is bad.
If it passes the first test...
1. With your meter still at the same settings touch the positive meter lead to the green wire and the negative meter lead to the black wire. If you get an "open" it's good.
2. Then take the positive meter lead and touch the black sensor wire while touching the negative meter lead to the green wire. In this case an "open" is bad. A reading somewhere around 300 - 750 Kohms is what you're looking for.

Informative as always..
I would say the same thing, but it's already been said twice.
