i did the same, but it was a flat driveway. Too much pride to ask for a jump.I have jump started my DL-650, three times. There was not enough power in the battery to turn over the motor, but enough to run the bike, once I got it started.
I pushed the bike, out the end of my driveway, and got it rolling down the hill next to my house. I "popped" the clutch, with the bike in second gear, and rode away.
I have also done this in a parking lot, with a slight downhill grade. MUCH harder!
