Checking the throttle sensor
NOTE: The following measurement should be taken when the
temperature of the part is approximately 20° C.
– Unplug the throttle sensor.
– Connect a multimeter (measuring range Ωx 1k) to the blue (+)
and black (–) wires of the throttle sensor.
– Now connect the multimeter to the yellow (+) and black (–)
wires of the throttle sensor.
– When the throttle twist grip is rotated slowly, the resistance
should vary evenly.
Removing and refitting the throttle sensor
– Unplug the throttle sensor and loosen screws 1.
– Remove the throttle sensor from the carburettor.
THROTTLE SENSOR RESISTANCE: 4 – 6 kΩ

– When fitting the throttle sensor, ensure that the flat section of
the throttle pin engages the throttle sensor slot.
– Fit the two screws without tightening them and adjust the po-
