I just finished instaling one of these on my 640 Adventure to replace the crapped out Touratech IMO. It works very well, but has a few little "quirks" you have to get used to. There is no LC4 "kit", but the KTM kit with the in-hose coolant splice will work. However, the coolant temp lead is *just barely* long enough to reach from the straight stretch in the frame to the dash of an Adventure. If you're mounting to the triple clamp, no worries. I bought the kit that was supposed to replace the stock KTM pickup, but it did not work on my forks because the brake disc was different, so I needed to make a new simple speedo pickup bracket to replace the one that was used with my stock KTM speedometer pickup. No big deal, just a flat piece of aluminum with a couple holes drilled in it. The screen with the trip odometer (screen #1) displays the ambient temperature instead of the coolant temperature. This pretty silly because the screen that shows coolant temp (screen #2) has a second tach display (digital tach in addition to the bar graph) on it where the trip odo was in sceen #1. It *really* needs to be hooked directly to a battery. Connecting it to a switched lead causes the trip odo and clock to reset frequently at power-up. However, connecting it to the battery causes the back light to remain on for 20 minutes or so after the last pulse from the speedometer pickup. I think the run-time counter also increments during this time. I doubt that it actually draws enough power to run down your battery in any way, but it looks kinda weird. There is an undocumented feature to change the total mileage and total run time - Defined sequence is entry of a secret factory factory code into the wheel size setting (9110); then user presses right button for 3 seconds to enter the first programming mode. To show that the computer is in the programming mode, the clock feature will flash. Then user can the press center button to get to the ODO and ART data, and enter the desired number. The computer will stay in this programming mode until the reset button on the back of the computer is pressed. Please note that user must the change wheel size setting back to primary WS for their machine. I found that I did not need to use the reset button to exit this programming mode, it would exit automatically once I had cycled through all the available parameters.
