Always bothered me that when I changed the oil I was not able to drain all of the oil out, just the oil in the tank. I tried the Scavenger system, worked great. After changing the oil I went on a 1000 mile trip, checked the oil when I got home and it was still golden. If your bike has stock pipes it is even easier. I have Doulble DD pipes on my Deuce, so I have to remove the aft pipe to hook up the drain tube, and a hot pipe is fun to deal with. I would recommend getting a couple of extra quarts of oil the first time you use it, until you get use to how much to let flow thru.
