1. Remove the standard linkage arm, making a note of the position of the shift lever.
2. Now fit together the HM Sensor with Shift Rod that has 55mm deducted from the total length to achieve the same overall length as the standard linkage. ( Rods are available separately under the accessories page)
3. Re-install the shift linkage making sure that the HM Sensor and the cable exiting the HM Sensor will not foul the gear lever or any other mechanism. It is preferred to fit the HM Sensor nearest the gearbox.
The HM Sensor has two female threads. These are special DUAL THREADS and each of these threads will accept a LEFT or a RIGHT thread.
1. The Sensor and Shift rod must be free on the rose joints. This means that you should be able to rotate the sensor and linkage rod at least a small amount on the rose joints.
2. The sensor and linkage rod must not hit or foul anything. Move the lever through its entire range of travel and make sure that the sensor and linkage rod are free to move without touching anything or straining the attached cable.
3. The wire exiting the sensor can be damaged by pulling hard or by cable ties being too tight.
Once the installation is complete, it may be desirable to do a test while the motorcycle is stationary.
This is a two part test.
Turn the ignition on and watch the LED. The current setting will be signalled once on the LED with either 1, 2 or 3 blips. After this signal, the HM Super Lite is in Normal Operating Mode. With the engine OFF, and while watching the LED push/pull the shift lever in the direction that would shift gearbox to the next higher gear (UP for road pattern and DOWN for race pattern). The LED will turn on when a shift is initiated, and will turn off again once the lever is released. The ideal sensitivity is when the lever needs slight more force than is required to engage the next gear. If the LED does not turn on, increase sensitivity until it does, just for this test.
Sit on the motorcycle and put it into 6th gear. Hold the clutch in and keep it held in for the duration of this test. The motorcycle must not move. If you can, also hold the brake on. Now start the motorcycle and raise the RPM to a steady 4000 RPM or above. While holding the engine at this steady RPM, try and shift into an imaginary 7th gear. Every time you do you should hear the engine RPM dip for a split second.
