How do I drain the oil out of the cooler when changing the oil? If I let it get pretty black before I change it, I drain all of it out of the crankcase and put some fresh in, after firing it up it looked used because I didn't get all of the old stuff out of the oil cooler and lines. Is there a dran somewhere or should I not even worry about it and just change it more often? thanks
