To change the speed sensor on a 2003 Harley Davidson Fat Boy, first, disconnect the negative battery cable to ensure safety. Locate the speed sensor on the transmission, typically near the primary cover, and remove the retaining bolt using a socket. Carefully pull out the old sensor, and install the new one by reversing the process, making sure to secure it with the bolt. Reconnect the battery and check for proper operation.
2006 Harley Davidson introduced the Dyna motorcycles with a 6 speed transmission, and in 2007 the 6 speed was added across the board.

The vehicle speed sensor is powered and monitored by theECM. The ECM processes the vehicle speed signal andtransmits this signal to the TSMrrSSM/HFSM and speedometerthrough serial data.The vehicle speed sensor is located on the transmission justbehind the transmission top cover.
speed sensor is located to the rear of the transmission chrome (retangular) cover. there are four bolts on the cover, if you are looking at the bike from the right side just behind the cover rear bolt is the speed sensor. loosen and remove Allen bolt with 3/16 Allen and rotate sensor just enough to pry out. it is in there snug. i just removed and cleaned my sensor. there were metal shaving. My symptoms were no speedometer , odometer, and turn signal not turning off after conmpleting turn.

Depends on the model. Mine will do around 120 mph.
A Harley-Davidson 4-speed transmission typically requires about 20 to 24 ounces of transmission oil, depending on the specific model and year. It's important to use the recommended type of oil, which is usually a lightweight transmission fluid or specific Harley-Davidson transmission oil. Always check the owner’s manual for the exact specifications and guidelines for your particular motorcycle model.
The crank sensor on a Harley-Davidson motorcycle monitors the position and speed of the crankshaft. It provides critical data to the engine control module (ECM), allowing for precise timing of fuel injection and ignition. This ensures optimal engine performance, efficiency, and smooth operation. If the crank sensor fails, it can lead to performance issues or prevent the engine from starting.
