Mad Dog's price is great and it really is a nice piece of machining.
That said, I know how to pinch pennies due to necessity. I orginally used a 2 liter soda bottle with the hole cut in the bottom that fit around the oil filter mount. Hold the bottle over the mount and start the bike. Have the cap off the bottle and a pan under it, making sure the bottle is angled so oil flows in that direction. Start the bike and run until clean oil starts to come out.
NOTE: EVO only, not twin cam... And if anything above is wrong please correct but it seems to work for me.
