There are several quick and simple ways to test the functionality of a Dynojet Quick shift sensor in the field for basic functionality both on and off the bike. The Push style sensor is easier to test due to the way they are activated by push. The sensors are activated by approximately 30lbs of force applied to initiate the travel of the rod into the sensor body to close the switch which makes a complete circuit and activates the fuel and or ignition kill to allow the quick shift. Since the pressure style sensors are basically just an open closed style electrical switch they are easily able to be accurately checked with a couple simple tools in the field.
Most commonly problems with intermittent activation are caused by improper linkage adjustment that may not provide the correct amount of travel to activate the sensor. We often find that the linkage adjustment works ok in lower gears, but may not work correctly in higher gears as the geometry of the linkage changes as you go through the gears, so it is critical to make sure the linkage is adjusted to work correctly in all gears.
On bike Testing for all style sensors
This type test is easily initiated by changing some of the configuration settings for the quick shifter within the Power commander Control Center software
Within the software you would navigate to the Quick Shifter Configuration menu which is located under Power Commander Tools, Configure, Feature Enables and Input Selections or use the hot key “Control F” which takes you directly to that list of features. Select the Quick shifter Configure button which brings up the Quick shift configuration settings. Go to the Minimum RPM setting and change that to 1000 RPM which is the approximate rpm speed where the vehicle idles. The next setting to change is the kill time, which you should change to the max setting of 255 milliseconds. Once these two settings have been changed you can perform the basic functionality test on the vehicle with it idling.
To perform the test start the vehicle and while it is idling normally you should be able to pull in the clutch (for safety purposes only, as the clutch is not normally used for quick shifting), and lift up or down on the shift lever, depending on which type shift pattern is used on the bike and it should either kill the engine, or cause a very noticeable hesitation. If the engine stalls or stumbles very noticeably that indicates the unit is working as designed. If the engine does not stall or hesitate then the next step is to check the linkage for proper adjustment or remove the unit from the bike for off bike testing.
Off bike testing for Push Style 4-130, 4-114-4-102 Sensors
- Simple battery Powered Test light or alternatively a VOM Meter
- Large channel lock pliers (not necessary but makes activating the sensor much easier)
