So the drive gear for the odometer broke on my WR450. I removed the drive gear ordered a new one and in the mean time installed an axle spacer and left the meter cable disconnected so I could continue riding. The new drive gear arrived, I installed it and went to reconnect the cable. Soon discovered that the internal drive cable had completely slipped out of the outer sheath while riding. Now I'm waiting for a new odometer cable...doh!
