My 05 fxdwg had the same problem. The MoCo had installed the wrong valve guide seals and it would use a quart in 1500 mi foul the plugs and it was always about 400 mi from home. I finely talked to the salesman after talking to the service dept (sd said it was normal for it to use a quart ) I said BS anyway the salesman is high up in the foodchain there and they replaced the VG seals. But that was in about 06 and still under extended warranty. There was a thread on JPCycle about it. Was very common for the 05. Mine quit using oil after that I was putting plugs in at 10000,18000 and 21000. Haven't replaced them sense and the bike has over 45000 now.

I had an 05 Road King. I didn't have this issue, but I was interested in it and I recall the MoCo was replacing the seals on 05's on their dime if it was proven the problem existed. I'd try the dealer and see if there's anything HD will do. If they deem the mileage is low enough for it not to be normal Wear-and-Tear, maybe they'll pop for it. Worth a try. The problem as stated is a defective valve-guide seal.

The valve guide seals themselves were not the problem. It was the installation. Per the MoCo, in some cases the valve guide seals were "side loaded" during installation. That is why some bikes did not have a problem, some had the problem on both cylinders, and others had the problem on one cylinder only.
My 05 was going through a quart every 1200 miles, all of it going through the rear cylinder. At about 4000 miles I replaced the valve guide seals on the rear cylinder only. Now well over 20000 and no more oil consumption.

Thanks again for all the replys... Its amazing to me that this site has so many different angles to one problem, its the reason I come here and search out issues and see how other people handled the situations.
I am purchasing my cams and cam plate from Fuel Moto, and I see they offer head service as well.

Pull the head, fix it right the first time. If you have some extra coin you can port and polish them, or you can clean up the ports yourself with a dremel and some time.
Another old mechanics trick is to stuff a crapload of rope down the plug hole and rotate the motor by hand up to TDC.
