It gets everything out 100%. First you drain the oil the normal way thru the two drain plugs. Then you hook up a hose and a cam filter of some sort. Stick one end of the hose into a new bottle of oil, start the bike and the old oil in the tank empties. Think of a blood tranfusion. Only for a M/C. Appears the only make it for HD's. Going to call and see if the make one for the R Star. http://www.roguechopper.com/   Logged     The administrator has disabled public write access. #316027 Aussie John (User) Gold Boarder Posts: 903 Re:100% complete oil exchange system 2 Years, 7 Months ago   So why by this when you could just screw the new filter on remove the return oil pipe let the old oil drain into a container and achive the same result.$70 saved and a oil change that takes half a day to do.I dont think any motors would have ever crapped themselves yet because of the little bit of old oil left in the motor,and if so they'd be every where,some of the old cars we had never got an oil change.maybe with a HARLEY (woo woo) you have to do this to keep them going,however R* will do 100000 miles anyway   Logged     The administrator has disabled public write access. #316039 texasscott1 (User) Two of a kind Platinum Boarder Posts: 2487 Re:100% complete oil exchange system 2 Years, 7 Months ago   It makes a difference if the Harley filter is on the return side of the oil flow. Ours is on the pressure side. If you want to flush the system some then after draining the oil, install the new filter, install the tank drain plug, leave the crankcase plug out, add a few quarts to the tank then start the engine and let the oil from the tank run out the crankcase drain. It'll only take a few seconds to empty the tank so don't let the engine run too long.

It has worked just fine so far!!   Logged     The administrator has disabled public write access. #316229 out2lunch (User) Senior Boarder Posts: 320 Re:100% complete oil exchange system 2 Years, 7 Months ago   If you find out that there's a system for the R*, let us know. I'd pay for something that allows the full replacement of oil. Frankly can't believe that you cannot drain most of the oil for an oil change. Ridiculous design but I guess that's the way it's designed.   Logged       The administrator has disabled public write access. #316235 texasscott1 (User) Two of a kind Platinum Boarder Posts: 2487 Re:100% complete oil exchange system 2 Years, 7 Months ago   Apparently it works on the Harley because they said the filter is on the return side. The Road Star filter is on the pressure side so if you try to interrupt the filter flow the bearings wouldn't be getting any oil. I posted a way to do it on our bike if you don't mind wasting a couple of quarts of oil. After you get through though you'd have to drain the tank again and then when adding oil add the amount recommended for an oil change without the filter. Not something I'd care to bother with every oil change especially if I was using $8/quart synthetic. Also, I don't know if it would hurt the return pump not having any oil to pump for a short time but it's something to think about.

No it doesn't and if you think about it the same thing happens with your car. There's oil left in all the oil passages, lifters, top of the head, oil pump, etc.. Just change it regularly and everything evens out.
