• Turn the cruise control power switch OFF;
• Start the bike in neutral;
• Depress and hold the SET key while turning the cruise control ON;
• Take your finger off the SET key;
• Now tap the set key once while listening for a click from the vacuum actuator and watching the red LED on
the front of the computer. If you hear the click and see the LED flash, tap the SET key a few more times
until the revs start to rise. Depress the RES key and the revs will drop. Some delay occurs with these
operations.
CAUTION: You need to be careful not to tap the SET key too many times as it is easy to over-rev the
engine if you tap it too often. If the engine revs too fast quickly turn off the cruise control
switch OR the bike's KILL switch. If the ECS (electronic clutch switch) is working
correctly it should protect the engine by shutting off the cruise control before such high
revolutions are reached;
CAUTION:
CAREFUL!
• When you are sure single taps work, depress and hold the SET key for a couple of seconds and see if
multiple pulses are sent to the actuator. Listen for clicks and look at the LED.
Checking the speed sensor: With the cruise in diagnostic mode, put the bike on the centre stand with the
engine running, engage 4
70 kph (45+ mph). Observe the LED on the computer to see it flashes regularly. It should flash quite slowly at
these speeds - at 1-2 second intervals.
Checking the ECS: With the cruise in diagnostic mode with the engine running, observe the red LED indicator
on the clutch switch and the LED on the computer. Quickly rev the engine by 'blip
LED's should illuminate briefly as the engine reaches 2,000~3,000 RPM if the engine starts from idle.
The slower the rate of increase of revs, the higher the revs required to make the LED light. A quick blip should
resulting in the LED coming on at about 2,000~2,500 RPM. A slow increase in revs may not see the LED
coming on until 4,000 RPM or more. When the LED's come on it indicates that the cruise control will be
cancelled.
Using the bikes throttle raise the engine speed to the same revs that would be used at typical 'cruising speed' ie
about 100kph (60mph), typically 3500~4000 RPM. The LED on the ECS should come on. Hold the engine
speed constant. The LED should turn off after 5~20 seconds.
If the LED does not turn off after 30 seconds, the cruise control may not work and the sensitivity of the switch
may need to be adjusted. The adjustment procedure is described in Section 12, Road Test and Adjustments.

Remember to wait at least 5 seconds after turning the cruise control off when in
diagnostic mode to then use it in cruise control mode – otherwise it stays in
diagnostic mode. It takes time for the capacitor which protects the computer from
surges in the power supply to discharge fully.
