Step 1
Remove the seat and the fuel tank. On most Yamaha models, all connections will take place under the fuel tank.
Step 2
Locate the speed sensor coupler The speed sensor is usually located onn the top of the gearbox and reads the revolution
of the countershaft. The three pole speed sensor coupler is situated 20/40 cm away from sensor, The connector is
usually accessible under the fuel tank or removing the side fairing. If the speedometer is driven off the front wheel, the
sensor coupler is usually in the headlight bucklet. If in dubt, check the Bike service Manual or ask your dealer for the
location of the speed sensor coupler. Confirmation:
Separate the speed sensor coupler, then rotate the wheels while ignition is on, the speedometer should indicate 0, if
so , turn the ignition off and proceed to the next step. If the speedometer registers a speed other than 0, you have not
disconnected the correct coupler and need to look again
