How did you check the oil on the dipstick? Screw it all the way in or just put it in until it touches the case? and.... How long was it tipped on it's side? If it was over for more than a few seconds oil will get into the head and around the valves, then when you start the bike up the oil will move into the exhaust and it will take a while for it all to burn out.
