Why change oil while its warm other then it drains faster? Personally I'd rather not deal with the hot headers that my hand is gonna be so close(touching) to. Hell I sweat enough here in Florida. I always pop the plug out then go get a drink or something while its draining. A couple extra minutes for cold oil to drain isn't gonna bother me none. If I leave a little oil in the motor,it wont make a difference if bike if maintained often. The difference in amount of oil drained between a cold or warm motor is minute.
