My genuine H-D parts manual calls it a "Clutch Inspection Cover Gasket", not a quad ring.

"it sounds as if your new Quad Ring is twisted . It should be flat or else you have no chance" That's the problem. Mine IS twisted, and seems to be made that way. The wide flat sides that go against the primary cover and the back of the derby cover/clutch inspection cover face the wrong way. It should be kind of like a washer, but it's the exact opposite, more like a band that is wider than it is thick. You can't just twist it into the right shape. It won't stay that way. I flattened it out by putting the flat side against a piece of cardboard and putting a thumbtack every 1/2" all the way around it to hold it in that position. Several hours later, I removed the thumbtacks and it immediately flipped back into its original position. I've decided it is a defective part. I'm going down to my local Harley dealer and see if they have one. One that looks like the picture would be very easy to put on. I see the four "pinch points" and if my seal were shaped properly, it should work fine with grease holding it in place.
Rob Roy's Revenge, mine does not look like your picture. The way it is laying in the picture, the flat side is not on the top and bottom, on mine it's on the inside and outside. I have seen it called many different things.

Thanks for all the help. It was becoming obvious that something was wrong with the new part I have. Bob

But, what about the old one that was there when you first opened it? Did it look like the picture?
If it looks like an OH and fits like an OH it should be called an OH dammit. LOL

Being soft it also can appear to be bigger than it needs to be. It can take a little patience to get it flat in place.

The old one was installed the way it is supposed to be. But part of it came loose when I removed the cover. It was completely flat, but after laying on a table for a while, it looks like it is trying to twist just a little. I found a local H-D dealer that supposedly has them in stock. Mine is a "James" part from J&P cycles. I'm going to go to the dealer and get the actual OEM H-D part, if it looks like it is supposed to. I'll get 3-4 of them if they have that many. I'll take both the old one and the new one with me. I can only see 2 possibilities here. Either I have the wrong part, or I have a defective part. It is clearly not designed to fit where the old one came off. It's the correct diameter, but it's twisted 90 degrees from the way it is supposed to be. I could just put the old one back and hope it doesn't leak, but I need to solve this problem. '06 is the last year for a carbureted Sportster, and I plan to keep it for a long time. I also have a 1989 FXRS Low Rider, and H-D no longer sells parts for it. Only thing you can get is aftermarket or used. It probably won't be long before it is the same for the Sportster too. It's possible the only reason they still have this part is that it is supposed to fit Sportsters through 2014.

I'm a carburetor guy, and have no desire to own an EFI bike. There is virtually nothing I can't get from the aftermarket for my 1989 FXRS, including complete engines and transmissions. Older Sportsters are more difficult to get aftermarket parts for. But mine is a 2006, and H-D does still have many parts for it. Probably not for much longer though. Unless a part also fits a much newer bike, they probably quit making parts for it some time ago, and are just selling parts they still have in stock. Unlike Japanese bike parts, about the only way to get real H-D parts is from an H-D dealer. There is a H-D dealer called Ronnies in MA that is/was selling oem parts online. People are still keeping Panheads, Shovelheads, Evos, and Ironhead and EVO Sportsters going. H-D has an aftermarket second to none.

I have noticed that just recently there seem to be Chinese made CV40 knockoff carburetors on the market. My theory is that since the last carbed bikes were in 2006, that patent rights for production may have lapsed and now aftermarket knockoff "Keihin CV40" are open to copying. Same as when Sam Colt's patents on the revolver ran out, a flurry of competition.
2006? Your bike is a wee lad compared to my 1991. Aftermarket exhaust systems seem to be the hardest parts to find for older bikes. Luckily, our motors are rock solid and not much has changed since mine was made.
Also, unless doing a clutch adjustment (rarely needed) you don't need to remove that cover. Just drain the primary fluid and refill through the inspection cover. One quart is all you need, you don't have to check the level. Just make sure you remember to refill it with one quart once you drained the old. I use Bel Ray STL, others choose differently.

Yes there is a lot of Chinese junk out there. But there is still some decent quality aftermarket stuff too. S&S makes carburetors for Sportsters through 2006.
Doing a clutch adjustment is what started all this. My clutch was not disengaging until the lever was almost against the grip, even when adjusted to the point where there was almost no play in the lever. After removing the cover, I turned the adjustment screw about one turn to the right to loosen it, then turned it back until I barely felt resistance, then turned it right 1/4 turn, and put the spring and locknut back on. Because of the gasket problem I have not been able to check it yet. If it still engages with the lever too close to the grip with the cable adjusted properly, do I need to loosen or tighten the adjustment screw under the cover?
