Waddup PDS! I dont know if you have already checked out the bike, but here at the dealership I work for we always look for signs of the bike being layed down (check for scrapes on edges of handgrips, exhaust, footpegs, and brake/shift levers/pegs). Start it up (make sure it does so easily), rev it a little bit to check the throttle response. Make sure brakes, levers, and shift peg all work. Check engine oil and also 2 big ones especially if the bike has been sitting a while... 1. Check the tank for BAD GAS (Been down that road) and 2. Check and make sure the battery is charged and working well.
Good Luck man!
