Just recently went from the stock 17/41 sprockets to 17/45 on my 04 DL1000 I am really happy with the better response off the line and at low speeds. It also makes overdrive more usable. My problem as you have probably already figured out is the useless info I now get from my speedo/odometer. I know that the 650's use a pickup off the front wheel/rotor. For all you mechanical wizards out there, would it be possible to customize the front wheel of the 1000 to be able to utilize the 650's sensor/cable assy? If it is possible, would I also have to swap out the whole speedometer unit?
