    It basically a casting drain plug for the cases, no need to mess with it, if you do and fubar it you get to buy new cases and spend thousands of dollars on assembly parts and labor and you dont' ride until its done.

    Unless you suspect your motor is sumping oil it's not necessary to remove that plug at any time.

    You have a dry sump oil system that recovers into the oil pan below the trans, so, as you were told

    Leave it alone unless you wish to temp the gods of repair!:injured:

    I tempted fate and took the plug out while doing an oil change. I got maybe an extra pint of oil out. I put some lock tite on it and put it back in no problems. I think to FUBAR it up yo would have to cross thread it or turn it until it goes into the case. For the amount of oil I got out I will most likely not mess with it again.:devil:

    Actually getting that dirty oil out of the crank case is not a bad idea. I do it about once a year. You don't have to mess with the plug though, just change your oil as usual and unhook a return line. Start the bike up and watch the oil that comes out into your pan until it turns clean, less than a quart. Turn the motor off, hook the return line back up, top off your oil and you are good to go. AL

    I do that as well with my softail, one thing I did get was the Scavenger system, its a bit pricey but it has a nice billet oil filter replacement that returns all oil from the filter area(I have a cooler) so I want that oil out too!

    Basically the billet piece screws on where the filter would and forces the oil to return to the motor, hook up a bit of clear hose to the return line to the oil tank and watch the black oil come out.

    The Evo unit is $50ish and my TC Softail was $70, yeah probably too much for what I got but, it works I could easily use a filter but figure by doing this i'm not pumping old oil into a new filter.

    The A motor is like $140 which I think is absurdly priced, but they do have some special fittings that you put on the bike that make it easier, but it's not worth that kind of bucks.

    If it were me I'd get the softail model for the tc as the billet oil return plug is the same on b or a motors. then just pop off the oil line like you did.

    that aint too awful bad if they are well made and last a while. I could justify it because, just think, getting all that dirty oil out of there is bound to extend your engine life. Now Im always getting the a's and b's bassackwards, on my 2002 Road King I believe I have the A motor?? AL

    Hey HotRK before we digress too far, let me pick your brain, is the 2002 RK an A motor or a B motor, suppose I could check the manual down in my shop tomorrow. What modifications were made to the B motor. AL

    Al...the RK and all touring bikes have the "A" motor. The "B",(Balanced) motor is exclusive to the Softail bikes. The A motors are rubber mounted in the frames. The B motors are hard mounted in the softail frames. The difference is, the B motor has rotating counterbalancers in the lower case. With the motor hard mounted in the softails, the counterbalancers eliiminate about 90%of the motors vibration.

    I also have the Scavenger oil flush system. It is very well made, CNC machined billet aluminum. After I drain my oil I usually get an additional 28 ozs of dirty oil. It basically works the same as what you do, but instead of pumping the remaining dirty oil through a new filter, you use the scanveger puck.

    After flushing out the dirty oil you put your new filter on and top off the oil bag. When ny brother saw how much dirty oil came out he bought one for his EVO.

    Ringo answered it correctly, B - softail - balancers
    A - rubber mounts -Baggers and Dynas

    The puck as Ringo dub'ed it LOL is a well made part, knurled on the sides for easy on and off, nice work, rubber o ring built in.

    Easy to to the work on a softail, the bagger setup comes with some fittings that go on you bike to make it easier to use when changing the oil.

    I'd call them to discuss, if dirty oil bugs you, then it's a good thing, especially if you run a cooler. Probably won't make an ant hills worth of difference but it did give me something else to do in the garage and extend my cigar time!
