Default Jumping Speedometer 2003 Fatboy

Hi, It is not the speedometer. I got a new one and it did the same thing.

The speedometer jumps around a lot. Sometimes it settles down and give the correct speed but not for too long.

The bike as 21k and is in excellent condition.

Most say it is the sensor on the trans (magnet) ?


Thanks in advance. LG

When a bear charges you at close range, and you have a shotgun in your hand, ready to go, it is not advisable to drop the shotgun and grab at a can of bear spray.
