I just use the same old "O" ring that fits in the groove in the outer primary cover. I just carefully wipe any oil off of it and the primary cover then press it back in the grove. Whenever I go by an indy I just stop in and pick up the gaskets I could use.

I've had my derby cover off about 12 times and my primary cover off about 4 times. I've never replaced either gasket, and never had any leaks.

Regardless of which gasket, it's a good idea to follow the bolt sequence and torque the bolts down to the suggested inch lbs.

that's odd. it should have come with the orange 'quad ring'. thats the oring, they call it quad cause it has 4 flat sides......

Not to be a wisenhiemer. A quad seal and an O-ring are not the same thing and shouldn't be confused with one another.
And a quad seal IMO is hands down far superior to an O-ring.

I was surprised when I put an aftermarket cover on my 09 about 2 years ago & took the stock cover off. They now use the O ring that will last for years but if you change the derby over to a non OEM you just replace the O ring with the old disc style gasket. The aftermarket covers are flat on the gasket side & don't have the groove.

I think you are wrong . I bought a new derby cover for my 08 RKC in Dec. Bought a new gasket just in case, since I have had the derby off a couple of times already. It is the flat round gasket on the left of your picture. My 03 FX still uses the rubber oring. Maybe something changed with the 09 and newer. Just saying what I got for my christmas present. Actually it is a 4 sided flat ring

Right on , Been using the same "O" ring gasket for ten years. Multiple on/offs, the only gaskets Ive changed on my bike is the Exhaust. And Ive had lots of things apart!
