Actually I watched them do the service. They drained the oil for about an hour then buttoned it back up. Refilled the oil, look at info from the ECM, and a finger check of fasteners. A test ride and some interaction with the customer (ME) and another fine job by the service dept.
Today the service guy had to hook up a computer to access the codes. Apparently the fuel pump's lower sensor has gone bad. The gas gauge won't work right until repaired. The part is on back order, but I can ride the bike anyway.
