You will need to find out where it is coming from.
If the bottom of the motor is covered after a ride it is likely that the oil is coming from the front of the motor.
The fact that you have changed oil recently would make me look first at the oil filter as a possible source.
The best thing to do is to get some degreaser, there are some good bio ones made from orange peels that work very well, and thoroughly clean the motor, especially the bottom, then start the bike and lay on the ground with a bright light and a clean rag and watch for the location.
Unless you have hit something it is unlikely that the main cases will be leaking.
The common leak points on these bikes are:
Oil filter..... Obvious
Shift lever seal.....Left side of motor between exhaust headers.
Cylinder head cover gaskets....obvious but the oil will be on your boots
Drain plug washer....You should use a new one each oil change. Usually only a drip.
Front main crankshaft seal.....The oil will be coming out from the little drain hole at the bottom of the timing belt covers.
Camshaft seals.....Same as above
Loose timing mark plug....On top of the motor near the back, seen from the left side.
Water pump seal....The oil will be coming from the small weep hole under the water pump.

There are other possibilities but these are the most common.

If you changed from conventional oil to fully synthetic oil it is not impossible that a tired seal is now letting oil pass since the synthetic migrates so much better.

Do some detective work and see what you find.

If the leak is not obvious on a clean motor throwing some talcum powder or flower at the possible areas will show it up better.

Sadly enough that is not uncommon. It seems like a weak point till you ask how many cars can be stored for half the year and still have an original water pump 25 years later?

The pump sits behind the case on the front of the engine that also holds the oil filter mount. The part you see is only the lower rad hose coupling and the impeller cover. It is driven by the same shaft that drives the oil pump and there are seals that keep the oil out of the water, and the water out of the oil. The weep hole is to let either escape without crossing territories since coolant in the oil is major bad, and oil in the coolant not much better.

It is possible that only the oil seal is leaking, but it is likely leaking because the bearings in the pump body are beginning to fail and allowing the shaft to move in other directions than round and round. :(

Drain the coolant (any oil in there?) and remove the water pump cover. Sometimes the bolts are frozen and some of them are quite long, so be careful not to snap them off. It's a good idea to place a brass or aluminum drift on the heads of the bolts and give the drift a sharp rap with a hammer to break any oxide bonding before attempting to remove the bolts. A slight angle from the axis of the bolt is best. This is good practice with all small bolts on these machines. If the bolt is stubborn another rap or two often helps. It's a real pain if you snap any of these bolts off so easy does it.
Once the cover is off you will see the impeller of the water pump. See if there is any radial or axial movement in the shaft. there will be rotational movement, likely 5 degrees or more but this is normal.
In order to effect a repair you will still have to pull the front cover which means draining your new oil and removing the radiator but you don't have to pull the engine as it says in the Clymer manual. You will need new gaskets and Pump and the associated seals and O rings. Sometimes the locating dowels are trashed and rusty and will need to be replaced.
Personally I would not go to the work of removing all these parts without installing a new pump. I also would use an OEM pump since I've read too many sad stories of premature failures with aftermarket pumps, especially those from one particular supplier who all but refuses to honor any warrantee.

The procedure for changing the pump is pretty straightforward and is found in any of the three manuals that cover these bikes, Honda, Clymer's, or Haynes, available from the "Manuals" tab at the top of this page, if you don't already have one. There might even be an on-line tutorial on one of the goldwing sites, I'm not sure.

It's not such a big deal, it's just sad that it should come with good fall riding weather on the rise.

We're here to help you if you need it.

There's a great tutorial with pictures on this site. Study the procedure and you should have no problems. One thing to remember, don't use an aftermarket pump and gasket. There are many out there but be sure to stick with OEM. You'll be glad you did.

If you've got oil coming from under the water pump's flange, take a serious look at the large O-ring that goes around the water pump body. About two years ago I replaced my water pump but in my haste and stupidity I failed to put that O-ring behind the pump's flange, around the cylindrical bearing housing. The bike always had a puddle of oil under it until I removed the pump and discovered the problem. Once I put that O-ring back in there, problem solved. The one inside your bike could be pinched or cracked which would result in the same thing.

Have a look at How to remove and replace your water pump - that article is for the 1100, but the 1200 is very similar.

You can find replacement parts here: http://partsfinder.onlinemicrofiche.com ... &A=85&B=11

Go with OEM parts only for this repair.

It could be the rear wheel bearing, or swingarm pivot/bearing, depending on where you're seeing the side play.

That nut is torqued on there fairly good, in the neighborhood of 70 ft-lb, if I remember correctly. An impact wrench would make short work of it.

There is lots of information on wheel bearing replacement in the manuals. You do have a manual don't you. Pay special attention to the splined coupling that joins the wheel to the final drive. When they get dry they fail so use the genuine 60% moly paste that Honda sells on these splines and on any other splines from the transmission back.
The bearing numbers are 6304 2RS and 6204 2RS and they can be found at any bearing supply or most auto parts stores. Try to get good quality bearings, NSK or TIMKEN or SKF. These bearings are a bit small for what they are expected to do so cheap offshore bearings will have a limited life.
Make sure that the bearing seat, the inside of the hub has not been ruined by the failed bearings.

Many people love the Dunlop E III but they, like most tires should be used in pairs. Lately the Korean Shinko tires have become popular. The Metzelar are pricy, like the Dunlop but those that use them say very good things about them. Generally, because the 150/80 X 15 size in a 77 or better load range is only made by a few brands so your choice is simplified.

Good luck.

Rear wheel bearing failure is best experienced at home. Not on the road!
